🎯 Mac & Cheese Success Tips
🧀 Cheese Selection: Use a mix of sharp cheddar and mild cheese for the perfect flavor balance. Freshly grated cheese melts better than pre-shredded.
📏 Portion Control: Adults typically eat 1 cup as a side, 1.5 cups as a main. Kids often eat more mac & cheese than adults!
🍳 Cooking Method: For large groups, consider making in slow cookers or large roasting pans. Easier to keep warm and serve.
💰 Budget Tips: Homemade costs about 60% less than boxed. For 20+ people, scratch-made becomes very economical.

Kids especially love it, so err on the side of generous portions.
