We use cooked potatoes, avocado oil, classic rice milk (unsweetened), salt & pepper. The avocado oil has a very neutral taste compared to other oils and adds a smooth texture. It's also great for the omega-3 health benefits. I use an electric mixer to whip the potatoes like my mom did which makes a big difference in getting a classic mashed potato texture. My extended family didn't even know they were vegan mashed potatoes until I told them and had the option of adding butter...

Sounds delicious, thanks for sharing your tips! I have always wondered about avocado oil, sounds like it might be a more versatile oil then I thought it could be!
