Caramelised Pineapple Rings

Doneness

Cut faces are deep golden brown with caramelised mahogany at the rim where the natural sugars have concentrated; flesh is fork-tender but still holds its ring shape with no collapse; the brown-sugar dusting (if used) has melted into a glossy syrup pooled on the surface, not blackened. The ring centre stays bright yellow — any ring with grey or translucent flesh has been over-cooked and is mushy.

Oil & seasoning

Brush 1 teaspoon melted butter or refined coconut oil on EACH cut face just before loading — bare pineapple stays pale and weeps juice instead of caramelising. The fat carries the brown-sugar topping (if used) into the flesh and accelerates the Maillard browning the bare ring would not reach in 8 minutes.

Season with: light brown sugar (½ tsp per ring, dusted on top), ground cinnamon, freshly grated nutmeg (a pinch per ring), dark rum (1 tsp brushed on after cooking, optional adult version), flaky sea salt to finish, vanilla ice cream or Greek yogurt to serve, chopped toasted macadamia or coconut flakes.

Watch out for

• !Use FRESH pineapple, not canned. Canned pineapple rings come pre-soaked in syrup and hold too much moisture — they weep liquid in the basket and never caramelise (the surface stays wet at 380 °F, sugars can't crystallise). Fresh ring at the firm-ripe stage is the only version this technique works on.
• !Pat the cut rings DRY with paper towels before brushing on the butter. Surface moisture from the pineapple's own juice is the enemy of caramelisation — wet rings steam through the cook and end up limp and pale instead of golden-edged. A quick blot per side fixes it.
• !Single layer non-negotiable — overlapping rings pool juices and the stacked rings stew rather than roast. Cook in two batches if doing more than 8 rings (each batch only 8 min so total under 20).
• !Watch the last 2 minutes — pineapple sugars transition from amber to bitter-black in under 60 seconds at 380 °F if a brown-sugar dusting was used. Check at 6 minutes and pull early if the topping has darkened past caramel toward the burnt-coffee shade. Better to under-shoot than over-shoot — bare rings can take a 30-sec encore; burnt rings can't be saved.
