Store all natural peanut butter, smooth or crunchy, upside down. Oil mixes in naturally, maybe one stir. It really works because I make oodles of PB & J sandwiches for my husband’s lunch.
Also, great tip for celery. A week ago I went to get some celery out of the fridge. It was not edible. I thought I had Pepperidge farm dressing, but I didn’t, so no dressing. Went w/ rice instead.
I wonder if putting it upside down would work for tahini, and at least make it a little easier to mix?
If you really need celery and you have some that’s limp, but not spoiled, cut a little slice off the bottom and put it in a glass of water for a few hours. Often it will crisp right up.
