This is dead easy, and your guests will hoover these up. And, it looks stunning. In Mexico, these are often served at Christmas.
You can make the "chips" (deep-frying the flour pieces) early in the day, so that the oil smell has the rest of the day to clear out of the air. As you fill up a couple pieces of paper towelling with chips draining on them, put another layer of paper towel on top of that and start another layer for draining. That saves counter space. When they've all had time to drain, put them without the oily paper towelling into a bowl, and set aside until you're ready for them later in the day. Then, just before you're ready for dessert, do the assembly. You can delegate assembly to a guest; I've yet to meet someone who hasn't found it fun! To drizzle the chocolate syrup, get a teaspoonful, and then tip the spoon slightly over top the chips and make circular motions. With any luck, most of it lands on the chips.
