Dearest All,

See this pan with frying butter inside ?

[attachment=1925]



Hmmm...nice eh ?....just ready to add some bananas and sugar and cream...or perhaps an egg and some eggy bread ?


...anyway.....why does adding oil to the butter stop the butter from burning ?


does it lower the temperature ?...change the chemistry....?...what does it do ?


Thanks


Neil

No-one's answered this (asked over Christmas) so I'll bump it!  [;D]

Will the oil float on top of the butter and therefore block the air (oxygen) from getting to the butter? Not sure - it's just a suggestion.

Thanks for attempting the answer Techmind !...sounds perfectly reasonable and perfectly plausible to me !!

......I do know it to be true as , apart from trying this myself I have seen many chefs mention this also.....so...it would be good to get the authoritative answer !!....if anything..........so that you can be smug in the knowledge of your excellent rationale !

Some oils burn at low temperatures some at higher temperatures so maybe that has something to do with it. maybe say like peanut oil burns at a higher temperature,different temperature then other oils! Olive oil burns at a low temperature! Maybe it changes the of burn  Temperature depending on what kind of oil you use.

If I fry anything in oil then I always use Toasted Sesame Oil and it doesn't
leave behind a bad smell like some vegetable oils do.
Also it fries well with butter too, stopping them both burn. I never leave
cooking fat though.
Rosalind Franklin was my first cousin and one my life's main regrets is that I never met this brilliant and beautiful lady.
She discovered the Single DNA Helix in 1953, then it was taken by Wilkins without her knowledge or agreeement.

Thank ewe Karen...yes..I thought this might be a ' change-of-temperature ' situation.

Mmm, I smell garlic... [;D]

Just wondered if it was anything to do with one being "animal" butter and one being "vegetable" oil.

Like Karen.W said, oils burn at different temperatures and I think butter also has a percentage of water where oil has none.

Not sure how included water would make a difference though. [:I]

THANK EWE That Mad Man

One might say that one could just as well turn the heat down then if by adding oil lowers the temperature but I am sure that there is more to it than that.

The food needs to be fried.....butter is used...and oil is added to stop the butter burning but the base of the pan must still be pretty much the same temperature. There simply has to be a chemical reaction as the two fats blend...without loss of temperature. It does only need to be a small quantity of oil so somehow the new blend of oil and butter retains the flavour and buttery goodness without compromising heat.....hmmmmm..I love garlic too !.....

Get a nice rib of beef, prang holes with a skewer....and insert whole garlic cloves on both sides every inch along and roast as you would..and then....oh my !!!.....are you in for a treat !!

I love your cooking tips... LOL Thats how we do the prime rib for new years day... I did not go this year..

But I agree with you.. I think the oil changes the makeup of the butter and stops it from burning!
