So who normaly cooks a Sunday Roast, then?

[Blandmum]

We have one 3 weeks out of 4 on average. We have the full deal, proper roast, roasted potatoes and real gravy. add on 2-3 other veg, and a gglass of wine for the cook . We all love it

martianbishop, I bet you know about non-Newtonian and Thixotrophic fluids too don't you?
I did denaturing of DNA and proteins in biochemical engineering - first year at uni. Why do broken DNA helices smell like wet dogs? (Not a joke, but I always wanted to know, cos that is what the stench was like in the labs )

If you think this is boring, wait until I start going on about lightbulbs.

for god's sake, get a room you two

And you can spot all the non-virgin girls when you do a DNA extraction cos they all go....'Oh yuck it looks like.....' and then stop and blush!

now sit down and tell me all about light bulbs!

mb, suzy sez we have to get a room first!
I theorised at length on why chicagomum's bulbs kept popping.

it must be the hydrogen sulphide that forms when the hydrogen bonds are broken then! but I thought that was rotten eggs, not wet dogs?
Wonder if anyone has analysed the make-up of the odour of a wet dog?

Isn't that a different sort of DNA extraction, MB?

No, not Hydrogen sulphide when the hydrogen bonds break. The sulphur in proteins is in Disulphide bonds which are different.

Not sure about the wet dog thing.....may have a google!
