Work quickly to shape the éclairs while they’re warm; if they firm up, return them to a 300°F oven for 2 to 3 minutes to soften and reshape. For extra crispness, bake the piped shells on a perforated pan or flip them halfway through baking. Ensure the cheesecake filling is not too loose by whipping the cream to medium-stiff peaks and folding gently to keep structure. If humidity softens the shells, re-crisp empty shells at 300°F for 5 minutes, cool, then fill. Flavor twists include adding 1 tablespoon freeze-dried fruit powder to the filling or using dark chocolate for the rims. Store assembled tacos chilled up to 6 hours and keep components separate up to 2 days.
