How does the Simmer Ring work?
Do NOT extinguish the stove, just drop it on (small end down) whenever you want to slow the burn.* It shields the edge of the Cup from the flame, cools the Cup, and slows the alcohol boil. It also reduces the air supply and raises the smaller flame much closer to the pot for maximum efficiency. For maximum simmer time, you can start the stove with the ring in place. The ring only continues to slow the burn with a pot in place to block excess oxygen from the jets. Without the pot, you may melt the ring! If you want a faster simmer, cut about 1/8″ off of the top of the Ring to let in more air. To simmer longer, make it a little taller (or lower the pot). A 3/4″ high ring, (1/2″ below the pot) seems to be a good place to start. Tests show that 1-1/3 oz. (40ml) will burn for about 40 – 50 min. 2/3 oz. (20ml) will burn for 18 – 20 min. 1/3 oz. (10ml) will burn for about 10 min. – heat 2 cups of water for perfect tea – no boil however. Phil Perkins so far holds the unofficial simmer efficien
