At the Get Stuck into Steak cookery class at The Jamie Oliver Cookery School they are so afraid of a little smoke that the pans aren't allowed to get hot enough to make a great steak. The chef has them hot for the demo, but you aren't allowed to go higher than 6. You are basically unable to replicate what they chef does, or cook a good steak. The 'Jamie Oliver steak-cooking style' amounts to hitting the meat with a bundle of herbs which even the chef accepted was ridiculous, and mixing the salsa verde on the board: just messy. Just google how to make great steak. You'll get a far better result. On the plus side the chef was nice and the other attendees were too and there's plenty of parking. A glass of wine cost £10.15.
