been using Patak pastes for ever and ever. Back when they were only in Indian markets ( USA )
I like them much better than the newer ( USA ) simmer sauces. they are available in every local market
where I live. ( NorthEast ) I used them ( many varieties ) as the paste I add to a SV bag for a
' curry ' chicken , pork , turkey . works very well that way , then i freeze the SV'd . rapidly cooled bags.
