When preparing mashed Stokes Purple sweet potatoes, what is recommended regarding the amount of liquid used to maximize pigment intensity?

Use less liquid than typically used for orange varieties.

A practical culinary tip specifically addresses maintaining the striking deep violet hue when preparing Stokes Purple sweet potatoes, particularly when mashing them. The intense color pigment is highly water-soluble, meaning that excessive addition of liquids, such as water or milk, will cause the color to dilute. This dilution results in a significantly muted lilac shade rather than the desired vibrant purple. To counteract this, the preparation advice is explicitly to utilize less liquid during the mashing process compared to what one might instinctively add for a standard orange sweet potato, thereby concentrating the color.
