Preheat oven to 375 F.
Wash, halve and pit apricots. Toss apricots with melted butter and add 2 tablespoons sugar. Toss well so that the sugar sticks to the buttered apricots. Pour into a baking dish.
In a small saucepan, blend ¼ cup sugar, honey and lemon juice. Scrape the seeds from the 2 vanilla beans into the pan and place the pod in for extra flavour.
Heat on medium just until sugar dissolves. Pour over apricots and roast for 20-25 minutes. While roasting, baste apricots with syrup, but agitate fruit as little as possible.
Serve apricots warm.
