This is a fun extra that pops up at the end of the game... It's muffin recipe that supposedly was the shadowking's favorite food. They sound tasty. Thought I'd put it up so people don;t have to beat the game to try it out (the CD had a hidden file called Muffin.txt )
Tim Cain's Chocolate Chip Pumpkin Muffins
-----------------------------------------
They're the Shadowking's favorites!
1 2/3 cup flour
1 cup sugar
2 tsp cinnamon
1 tsp nutmeg
1/4 tsp cloves
1 tsp baking soda
1/4 tsp baking powder
1/4 tsp salt
2 eggs
1 cup pumpkin (half of a 16 oz. can)
1 cup chocolate chips
1/2 cup butter (1 stick), melted
Preheat oven to 350. Grease muffin tins (one dozen regular sized)
or use baking cups. Mix flour, sugar, cinnamon, nutmeg, cloves,
baking soda, baking powder and salt in a large bowl. Break eggs
into another bowl. Add pumpkin and butter and whisk until blended.
Stir in chocolate chips. Pour over dry ingredients and stir until just
blended. Do NOT overstir! Scoop batter into tins and bake 20-25
minutes. After cooling, keep muffins wrapped in plastic to avoid drying.

I remember finding this file back when I first bought this game. My families been making them ever since and they are tasty!

I was a little disappointed this wasn't an extra for the GOG version of stonekeep, since I don't think you could find the text in the files anymore.
