One of the kids thought it would be a great idea to dump oats into the sugar jar since I said they could have a little sugar with their oatmeal. Then there were tears since it came up mostly sugar.
I thought I would have to toss it all, but then I remembered something I used to see my own sainted mother do when baking, which was use a sifter. I didn’t have to use a sifter, I just shook the sugar-oats out with a regular strainer into a mixing bowl. The oats were greatly reduced in sugar content and had maybe 1tsp a serving, while the sugar just had some oat powder left behind. Breakfast was salvaged for another few days (my children eat like the war horses at the local stable) and now I have a new kitchen task to train them on.
But the sugar jar is no longer in kid-reach.
