My new gas hob burns things. Is there a way to simmer?

Try a heat diffuser/simmer ring

Simmer

Ah thankyou. Riverwalk I didn't know there were such things. I will google.

I presume you are saying that the control knob's lowest setting is too fierce ? I have a similar problem and found that turning the knob back towards off, until there is just the smallest flame visible, was the answer.

Yes it is the same Normandy girl but I have it on the lowest setting.
Reading the cooker reviews should have warned me as this weakness was a main complaint.

Try Normandygirl's suggestion. You have to be careful as flame can easily go out while trying to adjust. Not all cookers allow you to do this.

I have it as low as it will go but it is still too fierce.
I will investigate a diffuser/simmer ring.

Are all the rings the same? Mine are different sizes and the back ones are simmer rings. If I try to simmer on the front, even turned back as low as possible things burn including my saucepan.

The rings are all different but the smallest is at the front.
I have just bought a diffuser from John Lewis. It was the last one in stock.
Looking forward to happy simmering.

You should find that the diffuser helps, Grammaretto.

Yes it has helped already!

I agree, sometimes called a flame spreader.

Sounds to me as if you need thicker bottomed pans!

If you know where you actually can buy a double boiler these days would you post the link?

I have wanted one for years and no-one sells them any more.

Have you tried contacting the firm that made your gas cooker about this problem, or the plumber that fitted it? The pressure is obviously too high, which could be dangerous.

If they say patronisingly that everything is as it should be, tell them to try cooking on the blasted thing, or if it is still under guarantee return it and buy an induction hob instead. They can be regulated.

grandtanteJE65. I googled 'double boiler pan' and came up with a couple sold on Amazon.

I am sorry, don't know how to do a link though.
