During this time off, I made something that's not food related. Bath bombs! I have to say, they are really great. They smell nice, and are very fizzy (and not $5 a piece like they are at Lush or some place like that).
1 part citric acid
2 parts baking soda (I did 1 cup:2 cups)
around 1 Tbsp. scent
approximately 1/4 cup water
2-piece plastic mold for shaping
In a mixer, combine both powders. (First two ingredients.... citric acid is a powder, and I actually found mine at an Indian spice store down by Pike Place Market) While mixing, carefully add the scent. (I chose lavender.) Add in some liquid/gel food coloring while it is mixing. About a tablespoon at a time, add some water while it is mixing. This can be kind of tricky, as you don't want the mixture to fizz too much (and never stop fizzing, and then not fizz in the bath.) but you do want it to be able to come together a bit. The goal is for it to look a bit like wet sand.
Then, take the two parts of your mold. and fill them with the mixture. Really pack it in there! When it's together, lay it out on some parchment paper or wax paper to dry. (This is also key; my old condo was way too humid to dry them out properly, and they did not fizz. It works best in an open area with relatively dry air.) Leave them out to dry, about 24 hours or so.
