This is a question with probably a very basic answer but how does your child take their food tech ingredients to school in the most lightweight but environmentally friendly way?
For example Ds has a recipe that requires a pinch of salt and a sprinkle of cinnamon. How should he pack this? My jar of cinnamon is more than half full so I can't just give him that and my container for salt is even bigger.
I haven't got enough Tupperware to put each ingredient in and I'd rather not use freezer bags each week. Ds weighs the ingredients out to save on weight (he doesn't want to carry 500g of flour in when he's only going to use 150g etc) also he worries that more ingredients = more chance of leakage.
