Just to clarify--when I originally proposed 30A outlets I was hoping
that 30A outlets were available in the 'normal' blade style (e.g. it
would look just like a 20A plug but would allow up to 30A to be drawn
through it, say for two griddles). Clearly that's not the case.

You could run 14/3 to an outlet and break off the tab on a duplex
receptacle. This would give you 15A to each plug. The loads on the two
plugs do not need to be equal.

With 3 14/3 cables this would give you a minimum of three duplex
receptacles with a total of 90A of potential current draw. You could
also add more outlets on each circuit for convenience.

You could run #12 but it's going to be bigger and more expensive cable,
and somewhat harder to work with. I did it in the garage, but I have
some tools that draw 15A so they needed it.

One other thing to consider is that once you start bundling cables
together you need to account for the heat. This starts to reduce the
allowed cable ampacity.
