Step 1: Prepare the Potatoes

1. Peel the potatoes and cut them into evenly sized cubes (about 1-2 inches). This ensures they cook evenly.
2. Rinse the potato cubes under cold water to remove excess starch.

Step 2: Boil the Potatoes

1. Place the potato cubes in a large pot and cover them with cold water. Add a pinch of salt to the water.
2. Bring the water to a boil over high heat, then reduce the heat to medium and simmer for 15-20 minutes, or until the potatoes are fork-tender.

Step 3: Cook the Garlic

1. While the potatoes are boiling, melt 2 tablespoons of butter in a small saucepan over medium heat.
2. Add the minced garlic and sauté for 1-2 minutes until fragrant. Be careful not to burn the garlic, as it can turn bitter.

Step 4: Mash the Potatoes

1. Drain the cooked potatoes in a colander and return them to the pot or a mixing bowl.
2. Use a potato masher or ricer to mash the potatoes until smooth.

Step 5: Combine Ingredients

1. Add the remaining butter, sautéed garlic, warm milk (or cream), salt, and pepper to the mashed potatoes.
2. Mix everything together until the potatoes are creamy and well-combined. For extra richness, stir in sour cream or cream cheese.
