Pressure cooking tomatoes and making ketchup

[bonkboo]

Perhaps I am over complicating things, but could you pressure cook tomatoes as part of making ketchup? Or does it not capture the depth of low and slow cooking?

Thanks

I would think the higher temperature of pressure cooking would give a greater depth of flavor for ketchup. Try both ways to find out. I've been pressure cooking to make tomato sauce for pizza and pasta and am pleased with the results. I use glass canning jars to hold the sauce inside the pressure cooker.

Do you use the tops as well? Or do you set the opened top jars on a trivet?

Thanks

FWIW..

I tried making sugo, in the pressure cooker. Um I thought it was, not capturing the low and slow method you are talking about.

You absolutely can. In fact, if you have a copy of Modernist Cuisine at Home, they have a caramelized ketchup recipe. And even if you don't, I'd say that's a hint that they consider pressure cooking the best method of getting the flavor out of the tomatoes.

The lids on loosely. I am following the Moderist Cuisine method for sauce. I have never made ketchup but if I did I would try their recipe as well. Not everything I have tried from Modernist Cuisine has worked, but the tomato sauce is one of the successes.

Actually the lids on more tightly works, except then the jars are pressure sealed and difficult to open.

The pressure cooker will not reduce fresh tomatoes, so after pressure cooking you will get cooked fresh tomatoes with all of their water. But you can start from a tomato puree and work your way from there.

My up-coming cookbook has a technique for making a pasta sauce using fresh tomatoes but the book is not coming out until September. : (
