Cook pasta, al dente, according to box instructions. Drain in colander and rinse with cold water to stop cooking. Place in large bowl.
Add remaining ingredients into bowl and stir to fully combine.
Taste and add any additional celery salt, pepper or paprika (or other seasonings) as desired.
Store in an airtight container overnight and serve the next day cold.
Notes
Pasta: feel free to use other pasta shapes! This is just how we have always served it. Also, feel free to use gluten-free pasta too!
Crab: the easiest option for crab meat is simple imitation crab, but fresh crab meat works great too (and is gluten-free).
Serve next day if you can: it tastes good right away, but it tastes even better the next day! Feel free to add additional mayo if you want to increase the creaminess!
Mayo: use whatever mayo you like best! I love this homemade mayo!
