When I first started making bentos for Lil’ C, I found that I was always throwing away leftover spaghetti sauce. I only needed a little for her bentos and never seem to be able to finish the whole bottle by the end of the week. Then I began to freeze them in an ice-cube tray. They work ok but I always forget how many cubes to use when I wanted to cook. Then I found a better solution – the lock-lock box! (see my bento supplies)
I find the little cubes to be the perfect size. Each cube is just the right portion for a day’s lunch. So now I freeze the remaining spaghetti sauce in the lock-lock box and just use 1 cube whenever I need it. No more throwing away leftover sauce!
I bought my lock-lock box at a Korean grocery store. So if you are looking for one, check your local Korean grocery store.
