"I practiced," was all he could really offer to reassure. He knew very well how risky it was to accept food from an Avenger, but he'd made this meal about five times now, and it wasn't bad. Not burnt, not weirdly smelly, just pretty good lamb. He was never going to be the sort of guy to cook every night, but he could manage it from time to time.
And the stove was not in flames. The lamb was all ready out of the oven, tented with some foil to keep it warm, and he'd even had time to clean the kitchen so it wasn't anything like a disaster zone. "Don't get used to it or anything."
