💡 Pro Tips for Perfection:
✅ Use fresh lemon juice & zest—bottled lacks brightness (roll lemons on counter first for max juice!).
✅ Low heat only—high heat curdles the sauce. Keep it gentle!
✅ Pasta water is liquid gold—starchy water emulsifies fat + cheese into silkiness.
✅ Low-sodium mastery (you love this!):
→ Skip added salt—rely on Parmesan for savoriness
→ Boost flavor with extra lemon zest and black pepper
✅ Blood sugar friendly (you love this!):
→ Use chickpea or lentil pasta (+25g protein/serving!)
→ Net carbs drop from 52g → 38g/serving
✅ Low-carb/keto option (you love this!):
→ Swap pasta for 16 oz hearts of palm pasta or zucchini noodles
→ Sauté zoodles separately 2 min; toss with sauce off-heat
→ Net carbs drop to ~8g/serving
✅ Extra richness: Finish with 1 tbsp cold butter swirled in at the end (you love buttery richness!).
✅ Make ahead: Best served fresh, but lemon-butter base keeps 2 days refrigerated. Reheat gently; toss with freshly cooked pasta.
