grits, water, butter, salt. that's it - it works. yellow /white/purple/green/pink, nadda problem. cook it up, thin with water as needed.
>>how to cook shrimp
okay, baffling a bit at TX, but...
apply heat - about 10 minutes or less
once the grits are done & adjusted for consistency - toss in the shrimp.
not long, they're done.
oh, overcooked shrimp make good pin-pong balls. not so much good eats tho.
steam up some fresh asparagus - good side/veggie for shrimp & grits.
