Party trick - my best friend's mum used to do this with oranges at parties. She'd scoop out the inside and replace it with orange or green jelly, then stick a little toothpick in with a paper sail so they looked like boats. Disappeared instantly!
This Watermelon Jelly Recipe is very simple and requires very little canning knowledge. (this is only my second time every canning anything.) This may not be a toast kin of jelly, But the uses for this jelly are endless. Salad dressing, on top of pancakes or waffles, Ice cream topping, Cake filling, mixed with yogurt, or on scones, biscuits or sweet rolls. and the list goes on.
