Purple Sweet Potato Mont Blanc

Hello all!

Sorry for the lack of updates but have been quite busy in May and probably the next 2 months too! But will be posting up recipes for some of the classes which I thought last couple of weeks. Incase you haven’t know (Well, I don’t think you’d know since I haven’t mentioned before), I have been conducting demo classes in Jaya Grocer in Intermark and Empire Subang on Sundays and Saturdays respectively. Not every weekend but most.

So, this purple sweet potato mont blanc was taught yesterday in Jaya Grocer, Intermark KL. Now bear in mind, all these are free demo where anyone can join in. Of course I am paid to teach but you don’t have to pay to learn. So after couple of months teaching, I tend to run out of ideas, it needs to be within 1 hour. something not too much of waiting time. something pretty, something that don’t need to be chilled to set too long before serving. So alot of them are small cakes, pastries and small tarts / pies.

Much to contrary beliefs, Mont Blanc is not THHHAAT difficult to make. It takes abit of effort. the original Mont Blanc calls for chestnut, but chestnuts are not that widely available and not many people appreciate chestnuts in desserts (ok like who likes sweet potato in a dessert anyway haha ) So I picked the sweet potato version instead of the original one.

Plus, it looks prettier anyway. Naturally purple without any addition of colouring.

So come that day of demo….. NO ONE knows what the heck is a Mont Blanc. Did I put too much hope on people would at least have heard of or seen it ? No. sigh. ok lah Mont blanc is a mountain. It’s also a pen. and also a dessert. I’m at least hoping my next crowd (in Subang) would know what this is :/

So here’s the recipe. It’s quite simple if you look at it. I used a Wilton Tip no.7 to pipe them. I used a multi opening one but I find it too fine, hence it’s hard to build height. Does anyone know which tip is used to make the creme for Mont Blanc ?
