The spice cubes, lemon cubes and ice cream all worked well. I felt the idea with me serving food is not new age, so I came up with another innovation. My idea is individualized peanut butter slices. Having peanut butter slices makes making a sandwiches a synch. It is a quick and easy way to put peanut butter on a sandwich.  Not only will you not get jelly in the peanut butter container, but it also forms the perfect portion of peanut butter needed on a sandwich.
