Greetings from Zagreb.
It’s Lješnjaci season. Hazelnuts. Do you like hazelnuts? I’ve never seen them sold like this in the USA but they grow and are harvested here in Croatia. These lješnjaci are out of the shell and sold in net bags. .
“Corylus avellana. Hazelnuts are sweet with characteristic slight notes of musty and earthy. One of the significant flavor mixtures found in hazelnuts is fiber tone. Filbertone is a naturally occurring ketone found in hazelnut oil. It has a roasted, marbled, sweet, and long-lasting character”
