Chef Tips from the Video
- Use a cold butter block and grate it into the mustard for a smoother emulsion
- If you prefer a milder flavor, reduce the mustard to 1 tbsp
- For extra crunch, sprinkle a pinch of sea salt on the potatoes just before roasting
- Line the baking sheet with parchment to prevent sticking and make cleanup easier
Troubleshooting
Potatoes are mushy after sous vide
Check that the water temperature was accurate; a lower temperature or longer time can over‑soften the slices
Sauce separates during layering
Make sure the butter is fully softened and blend the sauce until completely emulsified before adding to the potatoes
Bag leaks during cooking
Inspect the seal before submerging; re‑seal or use a fresh bag if any puncture is visible
Roasted potatoes are not crispy
Increase oven temperature to 210 °C or extend roasting time; ensure potatoes are brushed with enough oil or clarified butter
Storage
Refrigerator: Store leftovers in an airtight container for up to 3 days
