I learned this recipe from my Brazilian cousin Renata. It's made with lime juice, but since those come cheap in Brazil but not in most of the rest of the world, you can use lemon juice instead. The taste is best with limes though, so it may be well worth the investment! Plus, if you buy limes in bulk you can make caipirinhas or mojitos with the rest. It's a party!
Ingredients:
- juice of 2 or 3 limes, depending on how sour you like your lime pie
- a can of condensed milk
- 3/4 of a can of cream (just use the condensed milk can to measure it, Brazilian style)
- a roll of Maria cookies, or any dry-ish cookie you like, such as petit beurres or Betterfood
- 175g of butter
- 2 egg whites
- 2-3 tbsp of powder sugar
Pulverize the entire roll of cookies in the food processor, or if you do not own a food processor, like me, put them in a clear plastic bag and go ballistic on them with the rolling pin (or a hammer, or a baseball bat... whatever suits you). Put the cookie pulver in a bowl, and knead in the butter to make the pie's crust. The dough should be moldable and should not crumble too much, but should also not be too moist. Spread out the dough in a rectangular pirex bowl.
Next, squeeze the juice out of 2-3 limes. In a separate bowl, mix the condensed mild, the cream and the lime juice to form a homogenous, thick cream. Put the cream in the pirex bowl on top of the crust, and put in the refrigerator to cool.
Beat the egg whites with the powder sugar to a mérengue-like consistency. (Tip: a drop of lime juice helps to keep the texture foamy.) Spread out the mérengue on top of the pie, and put the pie under a pre-heated grill for 1-2 minutes until the top of the mérengue layer is golden. Chill in the refrigerator until served.
