Thank you guys for your response.
Well it’s quite a cool weather here in bangalore now. We have one of the most pleasant weather in india. Not too hot, not too cold. Unlike some other places in india that are perpetually hot like Rajasthan. Anyway there is nothing I can do about the weather. You think if I crumb coat my cakes with buttercream just the crumb coat it would make a difference ?
I do use ganache for some cakes that call for a chocolate flavour. But won’t want to use it for all cakes.
