Charlie shrugged in good humour. He didn't have much opinion on how Oliver did or didn't make the Puddlemere team work aside from being Ollie's friend.
As Oliver pulled an increasing amount of items from the case Charlie's eyebrows raised. It wasnt so much the amount of goods but the specifics of them. The rosemary plant in particular was a surprise. "Thanks, man. I'll have to try not to kill it, or at least use it up before ot dies. Although I wasn't usually so terrible at Herbology." He did at least recognise the sorts of things that could be theoretically be used for cooking steak. Not that he'd ever attempted such an activity.
"Oh! Yeah, that's easy enough though. It's a wood burning one," Charlie said before flicking his wand smoothly to bring in wood from outside, place it in the range, and light it. "Can't help you if yours is electric, mate. Sorry." He looked at the items again and focussed on the only one he wasn't able to identify. "The fuck is that thing?" he asked, pointing at the milky pale block of something rock-like included in the components Oliver held.
"I've never made steak by the way. Doesn't work so well in large families or communal living," he said. Oliver would likely understand the unvoiced certainty that his family hadn't had the money for steak, although the comment about communal living was true enough. They had had steak once in a while, but he hadn't been the one to cook it. "I'm a willing pair of hands though."
