Almond essence is well-suited to flavour cookies, cakes and marzipan. Since it is very strong, care must be taken not to overdose. If not available, kernels of peach or apricot can also be tried. Bitter almonds' usage in kitchen is mostly limited to sweets. They can, though, be used to flavour spicy dishes, thus giving a very exotic taste.
Careful dosage is essential and requires a lot of skill or practise.
