Satin Ice is my go to fondant. Mostly because it’s readily available in CA through various local distributors. Fondx from Cal-Java in So Cal and shipping would be very reasonable (I don’t like the Elite – the rasp flavor just doesn’t work for me). Look for both fondant and shortening at your local bakery distribution center. I’m sure you’ll find one in or near OC. (Bakemark, Dawn Foods, Qzina, Marque Foods are a few – just search their names, you’ll find them). Most will have a will-call pick up so you can place small orders. You can always get shortening at Cash & Carry warehouses but it’s not easy to find the no-trans fat hi ratio which is required by law in CA.
When a 20# bucket of Satin Ice costs $56 through a distributor, it’s much more cost effective than MMF.
