How to Make It
Melt the butter in a large skillet over medium heat. Add the sugar and cook, stirring, for 1 minute (the butter and sugar will remain separated).
Add the pineapple and cook, swirling the pan, until the pineapple is tender and the sauce is smooth, 4 to 5 minutes per side. Serve the pineapple with the sorbet and drizzle with the sauce.
