I've heard there are some good tasting ready-made fondants on the market.. I just find that MMF is easy to make, cheap to make and doesn't taste bad at all ... It handles pretty much the same way as the Wilton fondant but the advantage to MMF, is when it gets a bit hard, you pop it in the microwave for a few seconds and it will soften right up again .. it's really easy to work with and it tastes good to me
I've heard Satin Ice is really good too but it can get pricey.
I put 2 layers of buttercream under my MMF so that if people don't like the fondant (some don't like a chewy texture when it comes to cakes), they can peel it back and eat the regular icing ... the fondant's presentation is just so impressive to me .. such a beautiful smooth finish .. I really like working with it
