Step 2: First Layer
So first, you need to decide on what flavor of jello you are going to use to suspend the pineapple in. We have used just about every flavor you can think of over the years, from strawberry and green apple, to blue raspberry and orange.
Once you have decided on the jello flavor, make it with half the water the box calls for because you are wanting your jello to be nice and firm.
If the box calls for 1 cup of water, use half a cup.
If you are doing a large batch, essentially a double batch like we do, you would use 1 cup of water total.
Make sure to use good water, such as the water from a Brita Water Filter (see this instructable on how to refill your own Brita Water Filters yourself).
