A LITTLE HISTORY: Avgolemono is a Greek sauce made from eggs, lemon, and warm broth. Commonly added to soups for thickening, the sauce is used to dress up everything from roasted vegetables to fish dishes. “Vegan avgolemono” sounds like an oxymoron but it really is something that can be found in Greek cuisine, especially on the island of Crete. It’s called derbye, delbye, or alevrolemono and it’s prepared by initially mixing lemon juice and flour. When the mix is ready, slowly ladle warm broth in the mix. It’s used as a thickener to soups and stews during Lent.
