Lard, if her recipe for toad in the hole is anything to go by. But as Henry has been brought up on quinoa and carrot burgers, I’d expect him to prefer the food he knows best.
BTW, the SWs like to make a joke of Pat’s cooking, with Jazzer having to tolerate mounds of ratatouille at every meal when he was living at BF, but she isn’t a vegetarian, and they have their own home grown meat. I’m sure she can produce a decent roast dinner.
