Horchata de almendras (Almonds Horchata)

1/2 kg almonds
1/2 kg sugar (may use a bit less if desired)
1 lemon
1 cinnamon stick
1 pinch salt
3 liters of water (warm)

Grind the almonds (without peel) and bake in 1 liter of water with cinnamon, salt and lemon skin, boil 2 minutes only. Then strain the liquid through a sieve fabric. 

Once strained, return to boil the mixture plus another 2 liters of water. Boil for another 3 minutes. Back to strain.

To all the liquid we have obtained we add sugar and cinnamon powder.

Mix well and put almonds horchata in the refrigerator. Put it in freezer at least 1 hour before serving. Remove until you get a melting snow mixture, not frozen
