1-1/2 cup sugar
5 large egg yolks
3 large whole eggs
1-3/4 cups coconut milk
1 cup milk

Have ready a 9-inch round glass pie dish. Place a clean kitchen towel in bottom of shallow baking pan large enough to hold the pie dish. Fill the baking pan with enough boiling water to come halfway up sides of dish. Transfer baking pan to oven.

Place 3/4 cup sugar in a heavy-bottomed, medium skillet. Place over medium-high heat; cook until sugar begins to melt, swirling pan. Cook until melted and medium-dark brown, about five minutes. Remove from heat. QUICKLY pour caramelized sugar into pie dish. Swirl dish until sugar evenly coats bottom; let cool.

In a large bowl, whisk together remaining 3/4 sugar, salt, egg yolks, and whole eggs until combined. Add milk, coconut milk, and rum, whisk thoroughly. Pour mixture into pie dish. Transfer to hot-water bath in oven.

Bake 45-50 minutes. Remove from oven and let cool. The refrigerate at least 4 hours. When ready to serve, run a knife between flan and pie dish. Place a serving dish on top of flan and invert. Slice, and garnish with any remaining syrup.
