I used the lemon slice and wedge stamp first on white paper (lower left, upper two images). They are from Stamps of Life. That didn't leave much Kool-Aid on the paper as the images were outlines. Same thing with the stamp from Inky Antics on that same piece of paper. On those attempts, I used yellow embossing powder, lemon Kool-Aid, and yellow ink on the stamp.
I tried using a thick white embossing powder next, the upper right image in the group photo. I don't know if I held the heat too long in the area that looks like crystals have burned or if that was a clump of Kool-Aid that wasn't evenly mixed with embossing powder.
I got out a strawberry stamp, also from Stamps of Life, stamped the large and small berry with Stampin' Up Real Red ink, then embossed with a mixture of clear embossing powder that has a bit of sparkle in it with strawberry Kool-Aid. I used a white gel pen for the spots on the berry but they are a bit lost. The scent is much better because of the larger surface area.
What I like about the scents created with Kool-Aid is that there is a hint of the fruit smell, not an overwhelming cloud of it hitting you in the face like the candle or oil aisle in some stores.
I have grape, orange and tropical punch to play with and I'm suddenly thinking rainbows and unicorns. With a 3-year old granddaughter, this sounds perfect!
