A litre is too much mashed raspberries for any batch of buckwheat cakes I would make, Dorothy, assuming I would make any, which I almost certainly won't. It's way too hot to light the stove today, and likely to remain so for the rest of the week.

I do very little real cooking these days, and no baking. If I'm feeding only myself, steamed veg and frozen fish (cooked on a tray in the toaster-oven) seems to be about my limit. Bread is flat whole-grain buns that I freeze. Protein is eggs, cheese ranging from cottage to aged Cheddar, soup with beans in it ...

Soup. That's real cooking, but I don't do it often. Every soup recipe I know makes a big batch, which I freeze in litre containers.
