This is a question I've been wondering about for a while as a home baker and amateur food scientist. Why do recipes for whipped, fluffy desert components like whipped cream or buttercream icing always seem to call for powdered sugar? If I want to add sugar to a something, why would I also want to add the anti-caking agent (usually starch I think) for powdered sugar as well? Is that starch actually something beneficial for a whipped desert? Because as far as I can tell, the only time powdered sugar makes sense is when it's dusted on top of something or incorporated into a desert that is being mixed by hand and doesn't have the shear of a mixer to dissolve or emulsify the granulated sugar. And I've never had any issues just using regular granulated sugar and honestly prefer it to powdered sugar for icings, whipped cream and the like. If a recipe calls for powdered sugar, but it's being combined with a mixer or beaters I just use regular sugar and the results are great.

Anyone have any thoughts or experience as to what I'm overlooking? Or is it just a hold over from a time when electric mixers weren't common and you needed a finer sugar to incorporate the sugar by hand?

Over decades, it seems that there has been this evolving body of knowledge surrounding plating and presentation, which can only be absorbed fully, if you've spent several years at a high-end bakery or fine dining restaurant (swooshing a sauce with the back of the spoon, quenelles, 3-dimensional whitespace, etc.).

I'm an aspiring dessert artisan, and I'd like to get up to date on those principles, approaches, and techniques, without having to squirrel my way into the fine-dining lifestyle.

Instagram and pictures in cookbooks are great for inspiration, but I feel like I would improve faster by understanding thought process/vocabulary, than from analyzing finished products.

Any suggestions/advice/resources? (Most visual design books are too general imo)

Recently went to a Baskin Robbins, and I was surprised by how indecisive I was. I ended up going with a childhood favourite of mine (cotton candy), but it was far too sweet for me now. I'm curious, what are your favourite ice cream flavours? What interesting combinations have you tried? Any weird ice cream flavours you've tried before?
