Wouldn't that affect its taste?
yeah but it makes it taste better if using the right liquid.
also, water works fine apparently
Fill the bottom pan of your double boiler halfway with cool, clean water. Place the bottom pan on the stove over medium-low heat.
Cut the room temperature Gouda cheese into small, uniform pieces with a sharp knife on a clean cutting board.
Put the small pieces of Gouda cheese into the top pan of the double boiler. Place the top part of the double boiler over the bottom portion on the stove once the water has reached a slow boil, in about 20 minutes.
Stir the cheese every two to three minutes with a clean, wooden spoon until fully melted, approximately 15 to 20 minutes, depending on the quantity of cheese you wish to melt. Use the melted cheese immediately or keep it over a low flame until needed, no longer than 10 minutes.
