For the first time since I planted for their blossom three years ago , my almond trees are producing almonds. Much excitement and off I go to google what you do with a real life on-the-tree almond. Turns out there are two types- the sweet almond which is delicious and benign and the bitter almond which is evil and has cyanide in and will kill you. I have a vague memory that the nursery man said they were sweet almond but I would like to check and I can't find anywhere a guide to telling them apart. Any thoughts??
