Experimenting with #coffee additives. Today testing out coffee plus Tabasco and #peppermint oil.
Through all the ingredients in pre-filter, so it could be that some of the ingredients bind stronger to the membrane.
The smell of the peppermint has infused the room and there is a slight hot sauce kick.
Since I made the pot for two cups, it seems like the spiciness settled to the bottom and the second cup is hotter than the first one.
Might need to look into binding agents, since the peppermint flavor was lost with the second cup.
@johnabs will test out your suggestion with the foam, though just need to find a plant-based version.
@barefootstache in that case I would suggest soy lecithin
@barefootstache You can try it, but I doubt it will work since it's not really a surfactant. It's miscible in water, but I doubt it will form an adequate solvation interface around the lipid droplets to keep it in solution (like soap would, for example). It is also VERY hygroscopic, which doesn't bode well either.
I'm much more confident in the emulsion/foam idea, but try out glycerin and let me know how it goes! :)
