Strange confections and sundries in the grocery store's bread aisle.

Haven't seen almond bark over here, but I think that we have something similar (nuts & chocolate spread) called "nutella", and a number of copycat products, I believe that they are hazelnuts though.

Lemon curd is a very British thing. You use it like jam, and spread it on bread or toast. It is also used in filling tarts and putting layers in sponge cakes. Just about every store selling groceries would carry it.

Pumpkin butter? ..................

Never even heard of it.............. mind you, I have made pumpkin and ginger jam, which is rather tasty (it is sweet).

EDIT:

Rice cakes: the traditional British rice cake is flavoured with almonds.
