Brittle

Heat half of the sugar with the lemon juice and melt slowly.

When the sugar is completely melted, add the rest of the sugar so that it melts quickly, without burning.

Quickly mix in the nuts until they are completely surrounded by sugar.

Roll out the mixture with an oiled rolling pin on an oiled work surface (or between two pieces of parchment paper).

Let cool and break into pieces or crumbs for further use.
