Hello! I'm new to this! Trying to add my recipe for Blueberry Pancakes. The weight options for e.g. 1 tblspn of ground flaxseed is either 1gram or 100g. How do I add my own weight option? Also if I need to add 2/3 cup for an ingredient but the options it gives are either 1 cup of 100g what do I do??????? Thankyou.
