Group blog posts by category on homepage, with a featured post for each category

Hi there,

Please accept my apologies if this question has already been raised but I am unable to find it.

I am looking to accomplish this https://steroidly.com/

So I want to create a homepage that displays the "flagship" post for each category as a featured post, then has 6-10 smaller posts underneath each that are tied to that category.

I am using the Tasty site template as it seems to be the one that lends itself to this most easily.
