Enjoy and old-fashioned favorite. I have loved Knox blocks since I was a kid and was surprised to not see a recipe here. So I thought I would add one. For those who don't know what Knox Blocks are they are the original Jello Jigglers and I think a little more tasty.

So happy to have found this. My mom use to make these for me all the time when I was little and would get sick they were my favorite sick good and snack whenever. Over the years she forgot how to make them and lost her recipe. I made these tonight for the 1st time ever and I'm in love took me back to being a kid again. My mom was happy she said wow never thought I would get to eat another one of these. My nieces who are 17 and 10 years old never had them and they loved them as well and the 17 year old does not like hello but she loves these. I am over the moon that I found this recipe and it is so easy I will be making these a lot.

I had always made these for my children and had originally found the recipe on a Jello box. I always forget the ratios so this is a Godsend. I still make these and have adults that have never tasted one. They all love them and want to make them for their grandchildren. This recipe has surely stood the test of time!

I'm putting this in my recipe box (as I always have to look up the Knox to gelatin ratio when I make them). My only change is to make a small batch. 1 envelope of Knox is 3 tsp; so I use one small box of gelatin and 1 envelope plus 1 tsp of Knox.
