What's the ideal milk-to-sweet potato ratio for a balanced goguma latte?

The ideal milk-to-sweet potato ratio for a balanced goguma latte can vary based on personal taste preferences and the desired consistency of the latte. However, a common starting point is to use approximately 1 cup of milk / 240 ml for every 1 medium-sized sweet potato (around 7-8.8 oz / 200-250g) that has been cooked and peeled. You can adjust the milk quantity slightly depending on how thick or thin you want your latte to be. If you prefer a creamier and thicker latte, you can use a bit less milk. If you want a lighter consistency, you can add a touch more milk.
