I️ hc that Gabe is a great cook and makes dinner for Jack here and there. But Jack decides, one day, he wants to make Gabe dinner. And oh.... it’s bad.... Gabe keeps eating his portion bc he LOVES this man. But Jack just bursts out laughing at what a bad job he did and makes Gabe stop eating it, and buys his boyfriend dinner instead. Years later they still talk about the “one time Jack made Gabe dinner.”
I personally tend to stick to the hc that Jack’s pretty bad at first but at least learns how to make some reasonably okay meals with coaching. Like he’s the goddamn pancake master (the one thing he gets over Gabe on the ‘cool uncle’ ranking with Fareeha) and Ana and Gabe teach him a few recipes and honestly the only reason he takes to eating unheated canned beans and dry toast in his 76 days is Depression.
But his first attempts were… bad. Not good. Unpleasant. OVERDONE. And Gabe endured those largely on his own because everyone else learned to run and he… just can’t. He just looks miserable until Jack asks if he’s okay and he has to admit he was trying to will himself into not tasting while he chewed. They get take out a lot during Jack’s earlier exploration of culinary arts.
