My maternal grandmother is one of the most influential people in my life. She lived with us for the first 14 years of my life and continues to live next door to my parents in the house that will one day be mine. Grandma was my babysitter when mom was at work. Grandma taught me how to cook, sew, crochet and balance a checkbook to the penny.
Grandma makes energy bars. She is famous for them, friends of the family purchase ingredients so she will make energy bars for them. It isn't a care package from mom unless energy bars are being used to fill up extra space in the flat rate box. Energy bars are grown up rice krispy treats with oatmeal, raisins, peanuts, peanut butter and sesame seeds. Grandma uses a lot of peanut butter and peanut butter is not a cheap ingredient so she has a method for getting the very last dregs from each bottle...toss in some marshmallows and use them to srcape the sides of the bottle.
The same can be done with potato/macaroni salad and mayonnaise.
Do you have any tricks for getting the last drops from a bottle?
