Don’t use low-fat milk; the simmering can cause it to break. Also, don’t rinse or soak the potatoes in water once they’re cut. Doing so will wash off the starch, which is crucial for their creamy texture.
Don’t use a whisk to combine the ingredients for the batter; a large silicone spatula is better. A whisk incorporates air, which leads to bubbles rising to the surface during baking and marring the smooth, shiny surface. Also, don’t forget to run a knife around the edges of the cake the moment it comes out of the oven; loosening the edges from the sides of the pan prevents the cake from cracking as it cools. Finally, don’t cover the cake before refrigerating, as a cover may trap condensation that can drip onto the cake.
Don't substitute baby back ribs for the St. Louis spareribs. Baby backs are smaller and leaner and will end up overdone. St. Louis–style ribs are spareribs that are trimmed of excess meat and cartilage, so the racks have a neat rectangular shape. And don't be tempted to open the oven during the cooking time; leaving the oven closed traps steam, keeping the ribs moist and tender.
Don’t cook the pork until well browned all around. It’s fine if the pieces are slightly underdone and retain a bit of pink when removed from the skillet. The strips are small enough to finish cooking with residual heat after they’re transferred to a plate.
This was very tasty. Leaving the tails on and halving the shrimp after par-cooking them was annoying and messy. If the whole point is to add shrimp flavor it might just be easier to simmer the clam juice and shrimps shells together in a small pot to extract the flavor. I'd also cut the shrimp before cooking them so I don't have to slice greasy, slippery shrimp. Next time I might also drizzle on some lemon juice along with the finishing olive oil.
