I have a question about step 9 on the recipe "Foolproof Ice Cream" from Tammy. It says:
"Churn for 30 mins. If you have any add-ins, add to the ice cream for the last 30 seconds."
For flavor add-ins, like mint extract, how much should I put in?
Also, I am interested in making green tea flavored ice cream. What are your thoughts on that? Should I pour tea into the mix or the sencha/matcha itself?
