Place 1 tbsp minced shallots in a small bowl with 1 tbsp lemon juice. Set aside to macerate while preparing the rest of the ingredients.
Prepare an ice bath for shocking the peas after they have cooked. Bring 3-4 quarts of water to a rolling boil and season with salt until the water tastes well seasoned. Add peas to boiling water.
Boil peas for 3 minutes or until they start to get a bit soft.
Drain peas from boiling water and place them in the ice bath until completely cool.
Once peas have cooled completely, drain them completely of water and add the zest of half a lemon.
Grate or very finely mince the 1/2 clove of garlic. You should yield about 1/4 tsp grated/minced garlic.
Place the peas with lemon zest into a blender or food processor with the grated/minced garlic and 1.5 tbsp olive oil.
Blend or process the peas in short bursts so that some of the peas get pureed but some are left chunky.
Place the mashed peas back in a bowl and add 1 tbsp finely chiffonade mint and the minced shallots and lemon juice that you prepared earlier. Season with salt and pepper to taste. Set mash aside or in the refrigerator until ready to serve.
