Drain and rinse the almonds well.
Preheat oven to 350°F / 175°C.
Pulse the garlic in a food processor to mince. Add the almonds and remaining ingredients. Blend on high until as smooth as possible.
Spoon this mixture into a few layers of clean cheesecloth. Pull up the sides, twist, and extract as much of the liquid as possible. Unwrap the cheesecloth and form the pulp into a block or round (just make sure that it is the same thickness all over).
Place on a parchment lined baking sheet in the oven for about 40 minutes. The feta is done when the top is cracked and slightly golden. Remove from oven and let cool. Store leftovers in an airtight container in the fridge for up to one week.
