Creating fluffy mashed potatoes is straightforward if you follow these steps:

1. Peel and Cut Potatoes: Peel the russet potatoes and cut them into uniform chunks, about 1-2 inches in size.
2. Boil Potatoes: Place the potato chunks in a large pot, cover with cold water, and add a generous pinch of salt. Bring to a boil over high heat.
3. Cook Until Tender: Reduce the heat to medium and let the potatoes simmer for about 15-20 minutes, or until fork-tender.
4. Drain: Once cooked, drain the potatoes in a colander and allow them to sit for a few minutes to release excess moisture.
5. Mash: Return the potatoes to the pot and use a potato masher or ricer to mash them until smooth and fluffy.
6. Add Butter and Milk: Gradually mix in the softened butter and milk (or cream) until combined. Adjust the consistency to your liking.
7. Season: Add salt and freshly ground black pepper to taste. If using, stir in the minced garlic for an added flavor boost.
8. Garnish: Serve immediately, garnished with fresh chives or parsley if desired.
