52:10 The seeds of a fruit, if they are sweet (or otherwise good to eat – MB 202:23), their bracha is ho’adomah. (See Mishnah Brurah 202:23 for varying opinions. He says that all agree that if one eats the seeds after the fruit, the seeds are covered by the bracha on the fruit.) If they are bitter (i.e., not really fit to eat – MB 202:24), they are not considered significant, so if a person eats them, he does not recite a bracha on them at all. If one improves their taste by roasting or otherwise, their bracha would be shehakol.
52:11 Bitter almonds while still small are eaten mainly for the shell, which is not bitter. If they were planted for this, their bracha is ho’eitz. When they get bigger, they are eaten primarily for the bitter nut, so no bracha is recited. If one improves their taste by roasting or otherwise, their bracha is ho’eitz because they are fruit and they were grown with this intention. Almonds coated with sugar are ho’eitz, even if the sugar is the majority. Calamus (a root) coated with sugar is shehakol because calamus is not a fruit.
