I've become fond of blueberries this Spring. They're pretty inexpensive
at Trader Joe's - been paying $7 for 2 pounds - and I'd like to be able
to have them when they're out of season. Thus, a few questions:

Can I freeze them? I assume the procedure would be: freeze on a cookie
sheet or similar, double bag, store in freezer. If that's not right,
please correct me. How long would they last?

What are they good for and not good for once thawed? I've been having
them with other fruit and some of my homemade almond butter, all stirred
in a bowl. Mushy blueberries would do fine for this - not as good as
fresh ones, I'm sure, but they'd be good enough.

Can you bake with them, e.g., could you make blueberry scones with
frozen blueberries, and would you thaw them first or just put them into
the batter frozen?

Fruit smoothies - we know they'll be fine there.

Any other suggestions and "education" appreciated on this subject, e.g.,
if the whole thing is too much trouble and I just ought to look for
frozen blueberries in the grocery store.

Many thanks.
