Delicious! I use red and yellow beets only sometimes.
When restricted to root vegetables that require different cell wall breakdowns, moisture management becomes the primary challenge. Golden beets possess a high sugar content and dense fibrous structure that resists softening longer than starchy new potatoes. Starting both in separate pots of cold water ensures the thermal energy penetrates the center of each vegetable at an even rate, preventing the exterior of the potatoes from disintegrating before the beets are fork-tender.
Whisking extra virgin olive oil directly into white wine vinegar creates an unstable suspension that separates rapidly. The minced garlic and anchovy paste act as natural emulsifiers, utilizing proteins and starches to bridge the gap between oil droplets and water-based vinegar. Slice the cooked, peeled beets and potatoes to a uniform thickness of one-quarter inch to maximize surface area absorption of this savory dressing.
