Question: It seems like the hole in the center of this will still cause a "heat spot"~am I correct? Reviews on the 7inch says it flakes, same for this one?
Document: This almost works but it results in a hot spot in the center of the pan (where the hole is). I was able to make it work by placing a metal disk over the hole. So if there were no hole in the center it would be perfect--but, unfortunately, there is a hole in the center. So you would probably be better off to find one without a hole in the center--or you can place a metal disk over the hole to make this one work.
I wish I could say I love, it's heavy and well-made, but on my gas stove the heat comes up through the hole in the middle. So now I have a middle spot where pots get scorched, instead of scorching on one edge.Will buy one without a hole in the middle.
I had purchases two 7 inch diffusers and they work perfectly. I bougth this due to it's size and after using it once, I will not use it again. The hole in the middle does create a &#34;hot&#34; spot on the botton of the pan placed on top of it and due to that will burn sauces. Had this been solid, like the 7 inch diffusers, I am sure it would have worked just a well.
Good, though not great. Handle comes loose. Center hole creates more heat than I wanted. I rarely use it and choose instead the solid cast iron diffuser from Nordic Ware.
I have a side burner on my bbq that this thing works great for. Also works well on single burner butane. Still have some concerns about the concentration of heat at the central hole, but we shall see.
These Cast Iron Heat Diffuser with Handle are great for simmering. However, for every day cooking they are not the best. The hole in the middle lets too much heat on the center of the pot or pan being used. If this deffuser had slots where the ridges are and no hole in the middle this product would be great for regular cooking and simmering.
Fits my cast iron dutch ovens and larger skillets on the burner just fine. The toothed ring underneath provides stability on the burner grate. The hole in the center maybe lets in too much heat at that point but a simple piece of aluminum foil just laid over the hole takes care of that when it's a problem.
I liked the diffuser and am very pleased with it, except for one thing. I still had minor problems with simmering, but all in all it was much better having the heat diffuser than not having it at all. I would recommend it.
Since I bought a Tagine, this difuser was an imperative purchase. I didn't want my tagine to crack and the diffuser works perfect. I find the heat is well distributed in the tagine bowl. You should really get one of these if you like to cook in a tagine.
Since there is a large hole in the center of the diffuser, I tried to see what would happen if I turned the flame down to about 1/2 on. The water started to boil but only very slightly and only in the middle. I turned the flame down to about 1/3 on and the boiling intensity went up very slightly.
Answer: I have had nothing but success with this diffuser. THere is not a hot spot in the middle. When you use it on a gas stove the flame comes out of the stove in a circle bigger that the hole in the middle. Haven't had any problem with flaking. Worth the $. :)
