I only do tastings for weddings. I give a list of flavor combinations and the client can pick up to 3 flavors, 3 fillings, 3 icings and charge $30. If they want to try any other flavors, I charge $5 per flavor cake. Upon booking with me, I credit the $30 (or whatever total cost is) towards the total order price. I have a wedding tasting this Monday and on the 22nd…for the one on the 22nd she chose 6 flavors but this is because I have reworked my flavors so allowed them to choose more. Hope this helps.
