We guide you through how to cook eggplant correctly, with expert tips for choosing, preparing and cooking eggplant.

Eggplant — or aubergine, as it is also known — is an indispensable part of Mediterranean and Oriental cuisine and it has many fans, especially among vegetarians: large, plump, with feminine curves and in a dark purple skin, the elegant aubergine tries to impress every vegetable lover.

In terms of taste, however, it is by nature rather inconspicuous and has so far not really convinced many people of its potential for enjoyment. Many people have found them to be rather bland and often slightly bitter — and often this is because they are not chosen well or prepared properly.

Overview and nutrition

The aubergine belongs to the nightshade family and, from a botanical point of view, is a fruit vegetable — a type of vegetable whose fruits usually contain little fructose and are suitable for consumption. Because of its elongated, rounded shape , it is also called ‘eggplant’ .

Compared to other popular vegetables such as peppers or citrus fruits, eggplant contains little of the healthy vitamin C. Does that mean it is not healthy? Not at all: It is rich in various minerals that help the body to absorb other important substances better: Potassium supports your nervous system and manganese is an important component of enzymes. With 90 percent water content and only 17 kcal per 100g, it is also quite good for those who are keeping an eye on their weight. However, if there is plenty of fat involved in the preparation as a flavoring agent, calories are quickly added.

In addition to healthy minerals, unripe eggplants also naturally contain the poisonous and bitter substance solanine. Therefore, you should only use ripe fruits and preferably not consume them raw in order to avoid stomach aches and stomach upsets. Heating up destroys the natural toxin and makes eggplant safe to eat.

Rumor has it that eggplant contains nicotine. But is that really true? Yes, small amounts of the substance known from cigarettes are actually contained in the purple fruits – but not nearly as much as was claimed in what turned out to be an incorrect analysis. Further examinations in the aftermath confirmed: the amount of nicotine, at up to 100 micrograms per kilogram of aubergine, is just at the limit of what can be detected and is no higher than with numerous other types of vegetables.

How to cook eggplant correctly: choosing the best eggplant

Deep purple to black and about 20 cm tall – this is how you will find eggplants on every supermarket shelf. White, yellow or marbled varieties with a snake-like or spherical shape are not so common, but they are also represented in specialty grocers. Even if you can buy them all year round, the actual season is late summer heading into autumn — from August to October in the northern hemisphere — during these three months you have the best chance of getting your hands on the perfect fruit.

A good aubergine should be as heavy and plump as possible — that speaks for its freshness and a pleasant consistency. The shell should be shiny and free of cracks and scratches. The flesh should give way slightly when you apply gentle pressure. If this is not the case, hands off — hard fruits are still unripe, bitter and contain more solanine. Nobody wants that, so always choose mature specimens. Then it becomes soft, creamy and mild in taste when freshly prepared.

Expert tip: Thanks to new breeds, very few ripe aubergines that you can get in the store are still extremely bitter. If you have the opportunity, however, it is advisable to look around the farmers market for them — there are regional products with short transport routes. The fresher the fruit, the milder it tastes. If it lies around long after the harvest, it becomes increasingly bitter.

How to cook eggplant correctly: Correct storage

The best trick for delicious results: Process the fruit immediately. You shouldn’t buy an eggplant until you know for sure that you want to process it within the next 1-3 days. The longer it lies after the harvest, the more bitter its flesh becomes. But brownish-yellow discolored pulp indicates that the fruit is already overripe, and should be discarded.

Also important: the aubergine is delicate and has a small risk for frostbite. The vegetable drawer in the refrigerator is taboo. The damp climate in the refrigerator makes the pulp even more spongy and rather rubbery. Instead, you should store them in a cool, dry place, but please not for too long. In addition, the sensitive fruit is a loner who prefers to avoid contact with other fruits and vegetables. In addition to apples, bananas and tomatoes, she does not feel particularly comfortable because they give off ripening gases, which also make the aubergine ‘age’ faster.

If you have bought an immature specimen, you can leave it to ripen for 2-3 days at room temperature if necessary. This reduces its solanine content and you can still process it afterwards without hesitation.

If you’ve grabbed too many and can’t use the fruit straight away, freezing is also no problem if necessary. However, the following also applies here: the shorter you leave them, the better — so it’s best to put them in the freezer immediately. To prevent the peel from becoming bitter, it is best to freeze it peeled — that way you are on the safe side. After thawing, the consistency of the fruit is usually a little softer. They are best made into stews or pureed as a dip.

How to cook eggplant correctly: 4 steps for processing

The key factor in successful eggplant dishes is in knowing how to prepare eggplant correctly. We guide you through the steps for perfect preparation.

Wash and trim

The aubergine is used with the skin in most dishes. Therefore, you should first rinse the whole fruit thoroughly under running water. Then it has to be trimmed: The narrower head with the stem and leaf base must not be eaten, it is very bitter. Therefore, if you are using the eggplant as a ‘boat’, cut it off, leave the ends on and advise your guests not to eat the stalk with them. You can also cut off the lower end or eat it with you.

Cutting correctly

The simplest cut variant is round slices. To do this, place the fruit on a cutting board and cut even, finger-thick slices.

Cut the aubergine into even slices

To cut in half, you can stand the fruit vertically on the cut surfaces created by trimming and divide it lengthways into 2 halves.

Halve the eggplant

For elongated slices, place the halved fruit with the large cut surface facing down on a board, press it gently with one hand and first cut it horizontally lengthways into slices.

Cut the aubergine horizontally into slices

By dividing again in the opposite direction, you first get long ‘sticks’ and can then cut them down into even dice cubes.

Let the salt and water steep

Whether cut into slices or cubes, before you continue with the preparation, you should generously salt the aubergine. To do this, put the cut fruit in a kitchen sieve, mix it with 1 tablespoon of salt and let it steep for at least 30 minutes.

This procedure is particularly advantageous if the food is then prepared with a lot of fat — for example deep-frying or roasting — the salt removes water and bitter juices from the fruit. This makes the consistency more pleasant, the taste of bitter specimens a little milder and it soaks up less fat during preparation. Even if the positive effect of salt on the bitter substances in the fruit is controversial, salting is always worthwhile for consistency and low-fat processing.

Pat dry

To get rid of the excess liquid, you can line the work surface with kitchen paper, spread the eggplant pieces on it, and pat dry thoroughly. This makes them nice and crispy instead of limp and spongy. In this state, the pieces are now ready to be prepared.

What about the skin and the seeds?

You can eat both the skin and the seeds without hesitation. The small seeds run through the entire pulp of the aubergine. However, they are so fine that you won’t even feel them when you eat them. So you don’t have to remove them. They are neither harmful nor do they change the taste of the fruit. The skin becomes buttery soft when cooked, so you don’t have to remove it when you prepare the fruit while warm.

Expert tip: The only exception with the skin is pickled eggplant. In the vinegar brine, the dark skin can become bitter in the long run if you store it for a long time. That is why it is better to peel the fruit with a peeler or — as is usual with tomatoes — scald the fruit with hot water and peel off the skin.

Can you eat raw aubergine?

As a nightshade plant (including potatoes, for example), the unripe aubergine naturally contains the poisonous and bitter substance solanine. In modern breeds, solanine is usually only contained in very small quantities, but you should not consume the fruits unripe under any circumstances. If the aubergine has its well-known dark purple color and if you gently press it from the outside, it is ripe and you can prepare it without hesitation.

When heated, the natural toxin becomes water-soluble at high temperatures and some of it goes into the cooking water when it is boiled — so you should pour it away and not use it again.

Most of the available eggplant varieties are bred in such a way that if ripe fruits are eaten raw, no serious poisoning is to be expected. In order to avoid stomach ache and upset stomachs, it is better to use carrots, kohlrabi and co. They are much more digestible raw and also tastier than the rather bitter raw aubergine.
