This is the basic potato salad recipe you see at every Chamorro gathering or the village fiesta. I make it the way all Chamorros make it: in huge quantities. Everyone has their own idea of how potato salad should be, so you can be creative with this. Some like more eggs, some like less olives, and others omit the relish. Do what you want to make it yours. It's another need-to-know for Chamorro women. :P
Boil the potatoes and eggs (separately). Potatoes should be tender, but not too mushy or soft. I usually stick a tooth pick in to see if they're "just right." Peel potatoes and remove shells from hard boiled eggs.
Cut potatoes into little squares and chop eggs. (Some people prefer their potatoes chopped into large cubes, others like them smaller. My family likes the potato salad chunky, so the eggs and potatoes tend to be chopped bigger).
Empty the wet ingredients (the condiments: relish, olives, and pimentos) into a strainer and drain liquid. Mix together. Place mixture aside in a small/medium bowl. (It's up to you how you want this mixture to taste. You can add as much of one ingredient, or as little, as you want).
Using clean hands, preferably hands covered in plastic gloves, mix together gently (don't smash the potatoes!). They always say that only ONE person should be responsible for mixing the salad. Mix the dry ingredients (potatoes and eggs) in a large bowl, sprinkling black pepper over the mixture to taste.
Slowly add in the condiment mixture to the potatoes and eggs. You can add as much of the condiments or as little as you would like.
Empty entire jar of mayonnaise in and mix until ingredients are covered evenly. Use the second 1/2 jar to add in mayo as you want. The potato salad should be evenly covered and not too dry or wet with mayo.
Place salad into a large bowl or serving platter and use a spatula to spread the remaining mayo over the salad smoothly to decorate and garnish (kind of like icing!). You can decorate the top with hard boiled eggs cut into decorative shapes and little olives.
Serve cold or put in refrigerator and keep cold until it's time to serve.
