Input: [header] How to make cheese flan [title] Heat 1/4 cup water and 1 cup sugar over medium-high heat. [step] Use a heavy-bottom saucepan, which will help distribute the heat evenly and prevent burning. Stir constantly until the water boils and the sugar begins to dissolve. <sep> (A) [substeps] You can find milk-based flan in powder form at most grocery stores. If you are vegan, the lumps will be kept small. (B) [substeps] Before it melts, the sugar may begin to clump in the pan. Just keep stirring and moving it around and it will liquify. (C) [title] Pour in 1/3 cup shortening and whisk until white. [step] Keep whisking constantly until the shortening dissolves. (D) [substeps] Keep stirring until the sugar dissolves completely. The water will still be hot, so don't end up using an electric mixer.
Output:
B
