*Guest post by Derek A while back, my wife had a need for a double boiler to make her DELICIOUS Ham Mustard Sauce.  There are plenty of pre-made solutions for a bit of a fee, but we opted for ingenuity as opposed to cash and decided to make our own. What we ended up with was a pot half filled with water and a glass bowl set into it.  The key, though, is three toothpicks set at 1/3 radial intervals.  This allows the steam to escape but keeps it from escaping too freely. Just thought I’d share this handy, cheap tip. 🙂
