This is based on Ustard, that legendary stuff to which, if you add spices, yields bitter mustard, but if you add milk&sugar, turns into delicious Custard.
This product comes in a rectangular tray, similar to an ice cube tray, but with many more holes.
Each hole is filled with either bitter
spices or creamy milk and sugar -- and then -- covered with a thick layer of Ustard.
Simply take your spoon, pick a square, and mix thoroughly to see what you got.
Your goal is to find and eat all of the custard! When you do discover a custard, be sure to eat all of it, because printed on the bottom of the hole is a number telling you how many evil Mustards are lurking nearby.
And if you hit a Mustard, well, it's no big deal, but you do have to wash your spoon.
Available in the dairy section of your local supermarket.
