Put linseed, sunflower seeds and almonds into your blender or food processor. Blend at a high speed for 10-20 seconds, or until finely ground. You may need to stop and stir it around a bit to ensure you don't have any chunky bits.
If you're using a coffee grinder, do it one ingredient at a time and in small quantities, then mix ground ingredients together.
Store in a sealed jar in the refrigerator.
I made my batch of LSA with 3 tbsp linseed, 2 tbsp sunflower seeds and 1 tbsp almonds. Once ground, this made approximately 2/3 cup of LSA meal (more than the sum of its parts, gotta love that!).Nutrition information is approximate, per tablespoon.
