-Can play around with the ratio of liquid and/or substitute in some regular milk, just need a quart total of some milk and cream mix.
-Adjust sugar based on add-ins. Some may require extra sugar (tart fruit), some require less (crushed up oreos).
Use a large sturdy metal or plastic bowl. Pour the mix in the bowl. Whisking the mixture, pour in the nitrogen slowly, a splash at a time. You really want to make sure each splash is fully mixed into the cream. At some point you can start making bigger pours, but keep mixing each time. At some point you will also need to switch to the wooden spoon. Keep mixing! Total mixing time will be about 10 minutes, and note that it gets harder at the end. It is up to you to decide when the texture is right, but you probably will not need the whole gallon of nitrogen.
