You can sub out almond cream try any plant based cream you may have. A non sweetened yogurt works great. If you using a tangy yogurt increase white wine to 4tbs and add 1 tbs mushroom powder.
You can use a a can of whole coconut milk in place of the almond creme, but then be sure to add 1tbs of mushroom powder to help combat the excessive sweetness and coconut flavor.
Alternatively 2 tsp truffle oil can be used or 2 tsp truffle salt. If using truffle salt reduce the amount of black salt used.
To make the pizza oil free simply skip it in your alfredo sauce, add an extra tsp of nutritional yeast flakes to help add more flavor.
If you do not have black salt use sea salt and add 2-3 drops of liquid smoke, or add 1 tsp mushroom powder to help add a savory quality to your sauce
Yukon or Red potatoes also work well in this recipe, do not use any sweet potatoes
