Preheat oven to 250º and line a shallow baking tray with baking paper. It should be shallow so not much humidity builds around the broccoli. I use a scone tray with no lip at all.
1 T lemon juice
1 ½ T olive oil
½ t sugar
Cut 1 head of broccoli into flowerettes and mix with oil and lemon dressing.
Place on baking paper and roast 15 mins until cooked and partly browned. Do not overcook as the delicate flowerettes burn easily.
