1. Begin by placing the peeled and quartered potatoes into a large pot. Cover them with cold water, ensuring the water level is about an inch above the potatoes. Add a generous pinch of salt.
2. Bring the pot to a boil over medium-high heat. Once boiling, reduce the heat to medium and simmer for about 15-20 minutes, or until the potatoes are fork-tender.
3. While the potatoes are cooking, melt the butter in a small saucepan over low heat. Stir in the minced garlic, if using, and cook until fragrant, about 2 minutes. Add the heavy cream and warm it through, then remove from heat.
4. Drain the cooked potatoes and return them to the pot. Let them sit for a minute to allow excess moisture to evaporate.
5. Using a potato masher or ricer, mash the potatoes until smooth. Stir in the butter and cream mixture, salt, and pepper. Mix until the potatoes are light and fluffy, adjusting seasoning to taste.
6. Transfer the mashed potatoes to a serving bowl, garnishing with fresh chives if desired. Serve immediately.

Remember, the key to perfect creamy mashed potatoes is in the texture. I always say, “A good mash is like a good story—smooth, engaging, and with just the right amount of butter!”
