“Eat less sugar.  You’re sweet enough.”

The other day I stopped at the grocery store to pick up a few items.  My friend was with me.  I reached for a box of Knox gelatin.  “What’s that for?” she asked.  I told her I make sugar-free Knox Blocks for my husband’s lunch.  He’s diabetic and it helps stave off his craving for sugar.

Do we really want to go into a discussion of artificial sweeteners?   No.

Then she asked, “What are Knox Blocks?”  OMGoodness.  Have Knox Blocks fallen into the black hole of the past along with the horizontal and vertical hold on a TV?  Time to resurrect this amazing snack for grandchildren, for stronger nails, and for the heck of it.


Knox gelatin

Jello, sugar free or regular, two small or one large box



Place one cup of cool or room temperature water in a small, rectangular dish.  About a 7×9 or something like that.  Sprinkle 2 envelopes of Knox Gelatin powder on top of the water.  Walk away to your next task.


Next task.  Sprinkle the Jello powder into a 4-cup pyrex measuring cup.  Put in the sugar if you’re using the kind that needs sugar.  You can cut down on the sugar a bit and no one will notice.

Pour in boiling water up to the 2-cup line, whisking while you pour.  This may challenge your dexterity but I know you can do it.  When the water is in and the Jello dissolved, give the Knox mixture a bit of a whisk while you pour in the Jello mixture.

At this point I find that some of the Jello mixture is clinging to the inside of the Pyrex measuring cup.  I simply get a scraper and scrape it out and into the rectangular dish with everything else.  Place the dish into the fridge for a few hours.

At the end of a few hours, or overnight, cut the Jello into blocks.  Lift the cut blocks out and into a container with a spatula.


This is a great finger food for kids.  This is a great snack to grab when you’re looking for something sweet.  This is also a good way to bring Jello to a picnic or a potluck.

I wonder if this would work with bits of fruit in it?  I see another adventure on the horizon!
