Each week, the columnists of "La Table des bons vivants" answer questions from listeners from Europe 1. On Saturday, they share their tips on avoiding the sometimes bitter taste of cooked eggplants. 

It is a seasonal vegetable, which comes in many dishes ... But which frightens some, because of its bitterness. How to prevent an eggplant-based preparation from becoming bitter? This is the question asked by a listener of La Table des bons vivants to Laurent Mariotte and his columnists on Saturday.

Remove the peduncle from the eggplant

"The bitterness comes mainly from the peduncle, and the little dust that settles on the eggplant", explains chef Yves Camdeborde first. "You need a lot of leaves on top of the eggplant so that it can really grow and take on a nice color and flavor," he explains. However, the leaves of eggplants, of the same family as those of tomatoes, are poisonous. 

The chef's advice is therefore simple: "wash the eggplants well, remove the stalk, and after that don't forget one thing: wash your hands well, because bitterness is deposited on the hands and is transmitted very easily."

Chop the vegetables for a caviar

Another point of vigilance: do not let the oil in which you cook the eggplants, which can also be a source of bitterness, heat up too much. And one last tip, signed by Laurent Mariotte: when preparing eggplant caviar, it is better to chop them than to mix them so as not to crush the seeds, which also give a bitter taste.
