What preparation temperature range and time estimate is provided for lightly roasting purple carrots to preserve pigment?
Answer
Around 400°F (204°C) for about 15-20 minutes
To achieve the ideal balance between cooking the purple carrots until they are tender and preserving the delicate anthocyanin pigments, the recommended preparation involves roasting at a moderate temperature for a relatively short duration. The specific guidance suggests tossing them with a healthy oil and roasting them at approximately 400°F (204°C) for an estimated period of 15 to 20 minutes. This timeframe is sufficient to develop a slight char on the edges—indicating proper texture—while respecting the heat sensitivity of the primary beneficial compounds, thereby maximizing their final nutritional value in the dish.
