Last weekend, I was asked to bring an appetizer to a cocktail party. I wanted to make something a little bit different, unusual, something that would make people say “Wow, that’s unique,’ or “I’ve never seen anything like that before – fascinating.”
So I made liquid popcorn.
I tried it out on a few adventurous eaters, and got the desired response.
But at the party, the comments I got were “Ewww – that’s weird.” “Yuck – it tasted like popcorn, but the texture was like an oyster – and I hate oysters” and “I tried it, and I thought I was going to vomit.”
Obviously this wasn’t a foodie crowd. For fun, I might make it again for the LTH picnic. Clearly a different audience.
Liquid Popcorm
(All proportions are approximate)
Take about 3 qts. popped popcorn, and, using a spice grinder (in my case, an old coffee grinder reserved for spices) and, in small batches, grind popcorn into a fine powder.
Separately, add about 1/2 tsp. sodium alginate to 2 cups water, and mix vigorously in a blender. (Sodium alginate is available in consumer-sized quantities from
Willpowder.net.) After you let the mixture sit for a few minutes, it should be slightly viscous, and feel a little bit sticky. Add popcorn powder to the blender in small batches, until you reach the consistency of a thin crepe batter. (If there’s no vortex when running the blender, the consistency is too thick.) Add salt to taste.
Let sit overnight, to fully hydrate the alginate and allow any bubbles to disperse.
In the morning, dissolve 1 1/2 tsp. Calcium Chloride (available from Willpowder, or less expensively through homebrew suppliers) in 1 1/2 cups water.
Carefully slide about a teaspoonful of the popcorn solution into the CaCl2. It should start to set up within a minute or so. At that point, you can start to push it around a bit in the calcium solution. When it seems to be slightly firm, take it out with a slotted spoon and immerse in a water bath. It can stay in there for 15 – 30 minutes — much longer and the slight gel surrounding the liquid popcorn will thicken too much, and you’ll have popcorn jello.
Serve on a teaspoon, encouraging guests to take the whole thing into their mouth, and let it explode by squeezing it between the tongue and the roof of the mouth.

And make sure you’re serving it to people who are at least a little open-minded and willing to try something different.
Anyone else ever mis-estimated their audience?
