Place heavy skillet on burner and heat over Med-high heat. Toss in lots of butter some Thyme (including the twigs), salt and pepper saute until golden brown on both sides. Use some tongs and paint the tots with thyme. Yes you read this correctly....paint the tots with the thyme. After they are are golden brown place on a plate and your done. Note: if you like garlic you could add some to the butter and remove after a few minutes. Basically you're infusing the oil with a bit of garlic. Toss out garlic before it get dark.
What separates this from the traditional Fondant tots is one step. Traditional Fondant potatoes are fried to a golden brown just like above but are finished in the oven. Sous-Vide potatoes are Sous-Vide first then fried. Try the traditional ones by first frying them until a golden brown (like above) then adding a 1/2 cup of chicken stock to the pan and tossing it in a 425 degree oven for 30 minutes.
