The oddest breakfast
Just a simple recipe for a colorful omelette!
Warning! Only under adult supervision.
- purple basil;
- hot water;
- 2 chicken eggs;
- lemon juice;
- frying pan.
Dice some purple basil. Add hot water and leave for 5 minutes. Separate some egg whites from the yolks and divide the whites into two portions. Mix the basil extract with both portions of egg white – they turn green! Add some lemon juice to one portion – when stirred, it turns purple! Pour the whites into a hot pan, add the yolks, and salt to taste. Your colorful omelette will be ready in just a few minutes!
Purple basil contains anthocyanins. Their structure and color depend on the acidity of the medium they’re in. Egg whites are alkaline, so the anthocyanins’ structure changes in such a way that they turn green. Lemon juice makes the medium acidic, and the anthocyanins turn purple. Science even adds variety to a simple breakfast!
A similar experiment is included in the “Chemistry of plants” set from the MEL Chemistry subscription.
