Newbie question: steeping grains for an extract recipe

[WelshPaul]

Hi all, I have been asked to convert one of my recipes to an extract version for a friend of mine.
Despite having dozens of AG brews under my belt, I have no idea how long and what temperature the speciality grains should be steeped for, what volume of water/grain ratio to use, and whether or not all of the water from steeping should be added to the boil.

Thanks in advance.

Paul I followed Pitsys advice, 250g of cystal malt (you might need to adjust for others) in 1 litre at 66c for 30 mins, then add another litre and steep for 10 mins more.

If your adding several different grains, I can't help thinking you'll need about a litre for every 250g you use. Say you've used 6 litres in total for these grains, this will contribute to your total 23 litres (or whatever brew length your going for)
