Blowing In The Wind
Almond milk was used extensively in period; all existing cookbooks call for it, and it must have been found in literally every Medieval kitchen. It's the prime ingredient in many, many recipes, and the modern cook recreating Medieval food will have to learn its production in order to prepare the most common of dishes. Fortunately, it's easily made. I prefer the recipe of Terence Scully, as printed in Le Viandier de Taillevent, p. 315:
• 1 cup ground almonds
• 2 cups boiling water
Combine almonds and water. Steep for 5 minutes, stirring occasionally. Sieve the mixture to remove coarse grains OR (preferably) blend mixture in electric blender until grains are absorbed. Yield - 2 cups almond milk.
