Was trying out my new siphon with whatever was present in my kitchen:
a cup of skimmed milk, a few teaspoons of instant coffee, a few teaspoons of sugar and a bit of melted dark chocolate.
I used 1 cartridge of n2o first and shook 5 times. Didnt foam up a lot, so I used a second cartridge and shook it again. Foamed up a bit more, but not enough and foam collapsed quickly.
I was wondering if more fluid in the container, more shaking would work or if it simply needs an added ingredient?
