Bitter almond flavor comes from the seeds of the bitter almond tree, which contains compounds called amygdalin. When these seeds are crushed, they release a strong, nutty aroma and a distinct, slightly sweet taste that can be reminiscent of marzipan. However, the flavor is often considered too intense for direct consumption. This flavor is commonly used in various culinary applications, including liqueurs like amaretto and in some baked goods. It is important to note that bitter almonds are not safe to eat raw in large quantities due to the presence of cyanogenic compounds, which can be toxic.
