Another thing I sometime see in old cookbooks is reference to a "slow oven" or "fast oven" instead of temperature for the woodturning stove. And sometimes there are ingredients by brand name that you have never heard of. For example: 1 cup of Spry (What is Spry?) I found out later it was a brand name for shortening. The one my husband loves is my answer to his question "how long should I cook this?" I say "until its done." My father was a cook in the army in WWII. I have his old army cookbook. Each recipe is for "100 men."
