Step 1: Ingredients
Two Onion Pearls
Step 2: Prep and Cook
While waiting for the water to boil, quarter your potatoes and place them in a bowl. To prevent browning, cover the potatoes with water.
When the water comes to a boil, carefully add your potatoes (but not the soak water).
While the potatoes are boiling (which will take approximately 20-30 minutes depending on size/shape), peel and mince your two onions and place into your emptied potato bowl. To this bowl, add the zest and juice of one lemon and put aside.
When the potatoes are done, drain the water and leave the potatoes in a strainer to dry. Place the pot back on the burner and add your onion/lemon mixture. Sweat your onions - which means, cook until they begin to turn clear (this will take the onion edge off without bringing too much sweet flavor in). Now add your potatoes and enough mustard to lightly coat. Mix well.
