How to keep pork crispy during transport to venue?
Being Filipino, I totally applaud you for such an excellent choice of an entree. The enemy of all fried food is moisture. Think of...potato chips. Immediately after you fry, make sure you let the food cool at room temperature before packaging. I would store the lechon in a non air-tight container, like a KFC bucket/box with parchment paper. Paper bags are good options as well. After the food has substantially cooled, feel free to refrigerate. Don't put your lechon in a sealed tupperware container while hot, as condensation from water evaporating from the meat while it is hot will often form and make your food soggy. Bring on the Mang Tomas and have at it.
