Mr. Castro will be familiar to fans of “Broad City,” the Comedy Central show in which he played the hysteric gay roommate Jaime (pronounced HI-may). In real life, the actor is far mellower than Jaime, though he is every bit as quick-witted.

He now stars on his own sketch comedy show, “Alternatino” — he is also one of its writers and executive producers — which takes a humorous look at being a Latino today. It finds laughs in cultural clichés and stereotypes, and even in the fun-house mirror horrors of Trump-era politics.

One sketch, for example, addresses the immigration crisis at the border. Playing a blond immigration agent named Bryce J. Korn, Mr. Castro extols the conditions under which children are being held after being separated from their families.

They’re not in cages, he explains, but “free range.” In the background, detained children wander a field fenced in with electrified barbed wire.

“I’m not a very politically motivated person, but that changed when they started caging kids,” Mr. Castro said, his cherubic face turning suddenly serious. “Having a platform, it would be irresponsible not to say stuff like that. This is a Latino show, that’s my angle. And if the comedy pushes buttons, well, that’s the point.”

Ms. Hada had Mr. Castro measure out a half-ounce of agave syrup, explaining that it’s best to build a drink starting with the least expensive ingredients first. “That way if you mess up, you don’t have to pour out all the mezcal,” she said. Next was lime juice, then passion fruit purée and ginger beer.
