Last weekend we were visiting friends in Germany and my Daughter and I got bitten by mosquitoes, and since we are both allergic to them we were full of swollen lumps. DD also took a tumble and sported an impressive bruise on her knee... but my friend Tatjana came to the rescue with this simple remedy. It's surprisingly soft and comfortably cold without the chilling lumpy frostiness if ice and it recycles cherry pips, so is also environmentally friendly. I tried to enter cherry pips in the ingredient list but that's not possible, but you will need between 1/2 lb and 1 lb (250-500g) of ONLY the pips of the cherries not the actual fruit, so when cherries are in season, start saving those pips instead of throwing them away! Can NOT be used as a heat pad, so please don't try microwaving it. Prep time assumes that you have a heap of cherry pips cleaned, dry and ready for assembling the bag.
