Pineapple-Juice-Can Hen and Baby Potatoes

Roast chicken is one of my I-can’t-have-it-around-or-I’ll-eat-the-whole-thing addictions. After the first meal, the rest of the bird sits front and center in my refrigerator, and when the urge hits, I pull off a piece here and there until the carcass is picked clean. Anyway, that’s one of the reasons I am drawn to smaller birds: guinea hens, squab, poussin. They’re certainly on the high end in terms of fat and calories, but at least when I’m done, I’m done. No more temptations. When I saw 3/4-pound hens at one of my favorite vendors (Eco-Friendly Farms) at the Sunday farmers’ market in Washington’s Dupont Circle, I had a brainstorm: Why not treat them like beer-can chicken (more colloquially known as beer-butt chicken), but with a smaller can of pineapple juice instead? I thought it was the most original thing ever, until I Googled around and saw that others had trod this ground before me, including barbecue maestro Steven Raichlen. I forged ahead, combining the pineapple with one of its natural partners—rosemary—and cooking down extra juice with lime and butter into a sweet-and-sour glaze. With roasted potatoes (babies, of course), I had a meal.
