Can Muslims eat French nougat

Yes, they can. French traditional nougat recipes use sugar and honey, almonds and less frequently other nuts (hazelnuts, pistachiOS, walnuts) and egg whites and sometimes candied fruits. The brown nougat recipe is bristle and crunchy as it doesn't have the egg white addition. Both recipes are acceptable for Halal diet, contrary to English or American nougat-like candies, which most often contain Gelatin and additional fats.
