Rissetree 6.75 Inch Cast Iron Heat Diffuser Plate - Simmer Ring, Heat Tamer and Flame Reducer for Gas and Electric Stoves
A solid 6.75-inch cast-iron plate that sits on the burner grate and evens out a flame that is too concentrated for the pan on top. Cast iron is the heaviest and most stable version of a heat diffuser, so it doubles as a flame tamer for sauces and a small trivet beside the stove. Built for gas and electric burners - it will not work on induction - and sized for the single-burner and two-burner propane stoves most car campers cook on.

The same problem the steel diffusers solve, one pot at a time: a propane burner puts its heat in one ring, the pan center burns and the edges stay raw. Cast iron fixes it with weight - the plate absorbs the hot spot and releases it evenly - and it is the version that will not slide around on a windy picnic table.
🏆 How It Compares
The heavy, no-frills half of the diffuser class. The Cooks Innovations SimmerMat is lighter, bigger (7.87 inches) and dishwasher safe on any cooktop including induction; this Rissetree plate is smaller, cast iron, induction-incompatible and $20 cheaper, and it holds its place on a grate better. Buy the steel one for a wide family pot on a two-burner, the cast iron one for simmering sauces on a single burner.
Pros & Cons
✅ Pros
- Solid cast iron evens out a hot ring on a propane burner and stops sauces scorching or boiling over
- Stays put on a camp stove grate because the plate itself carries the weight
- Doubles as a small trivet or pot rest next to the stove when it is not on the flame
- Simple, uncoated metal - nothing to peel, chip or re-season beyond a wipe of oil
❌ Cons
- Not for induction cooktops - gas and electric only
- Heavy for what it does, and it needs to come off the burner to cool before packing
- 6.75 inches is a small-pot size; a wide griddle or a 12-inch skillet overhangs it
