You can get rockcarrots from jungle ferns just go harvest jungle ferns like so starters can see

Make a dodo egg farm, vegetable farm and irrigation

You can get rockarrots by searching bushes, they aren't rare, but they are a bit uncommon.

You don't actually need engrams for it you just put the ingredients into the cooking pot and lite the thing

Make medium plots for carrots over 300 carrots now

Fertilized dodo eggs dont work unfortunately so you need to wait for your female dodo to lay a normal dodo egg

Dodo has a chance to lay egg everytime they poop... Let's abuse this!!

Farm some berries, especially Stim berries, it'll make them poop...

Tame a dodo, forcefeed them the stim berries, enjoy your "Unlimited Pteranodon food"

Use a trike or a herbivore to gather rock carrots I used a trike and got a bunch

You can just scramble the ingredients up and u can still make it.
