“It’s a good time to stock up on what you might want for the year.”
I didn’t know that! I’ve been shopping for at least four decades, how did I not know that? Well better late than never.
Cornstarch, salt and baking soda have an infinite Shelf life. So stock up on those, store them appropriately, and they will be there when you need them. Cream of tartar might as well.
For baking powder, which does have a finite shelf life, you can substitute baking soda and cream of tartar.
In store my baking powder and yeast in the freezer.
They do fine that way.
One thing I always look for on sale at this time of year is chocolate morsels. They always go on sale and I stock up on mini morsels which we use in homemade granola and zucchini bread.
Flour, sugar, and butter typically go on sale now, too. I’ve gotten great values on pie crusts as well.
Lots of people are doing holiday baking, particularly Christmas cookies. That’s why I’ve noticed the sales on baking supplies.
