Peel and clean your 6 large potatoes. I like using Yukon Gold potatoes or even Fleshy potatoes.

Cut all your potatoes into 1 centimeter pieces and place into your season pot of water. On high heat bring your potatoes to a boil. You just want to par boil them. Just enough so that they fall off of your fork.

While the potatoes are boiling, finely chop your onion.

And do the same with your celery.

Once your potatoes are done strain them off and place into you refrigderater until they are cold. About an hour or so. This is so they stop cooking and keep there shape.

Once cooled, add your pea's, onion's, and celery to the potatoes. Give this a little mix. You don't want anything clumping together.

In a separate bowl mix your mayo, cider vinegar, mustard, sugar and your salt and pepper.

Add the sauce to your potatoes and really give it a good mix. Making sure you cover everything. Now your ready for that picnic. You can add a little parsley for garnish if you like. Enjoy.
