You know Kale! Hey, Everyone talks about kale as the hottest since, well,… ever. This leafy vegetable reached celebrity status around 2012 where Bonappettite magazine named “The year of Kale”. and the United States declared “National kale Day” on October 2, 2013. Kale displaced any other form of greens in soups, salads, pesto, and cooked vegetables and even showed up in pre-packaged snacks at the grocery aisles. 9 years later, kale is still in the front line, and you’re still loving it as much as I do!

Sweet Potatoes began its ascension in the 2000’s for one big reason: The fad diet. This hearty sweet potato is Godsend to the Paleo diet, South Beach, or Atkins diet. Their hundreds and thousands of followers touted it as a superfood. Hungry people including me and maybe you too, health-conscious eaters, and local foodies all add up in these factors.

Tarragon has long been prized for its aromatic leaves. One of the herbs used in the classic fine herbs blend, a mainstay for French cuisine.

French tarragon is actually Thomas Jefferson’s (the third president of the United states) favourite culinary herb and tarragon vinegar was used to dress his salad.

How to prepare kale for salad?

Preparing kale for salad is the same as making a regular salad. Except, kale needs a little attention. Tuscan and curly are the most popular kinds of kale but they have different characters.

Curly kale has a harder and stronger texture. After you strip the outer leaves from their center vein and chopped, drizzle with a little olive oil, and toss while giving a gentle massage. This step is necessary to soften the leaves. Also, I highly recommend letting it sit for a little bit before serving to develop a more pronounced flavor and feathery texture kale.

Tuscan kale has softer leaves and a lighter flavor that doesn’t need a massage but you should give some time to sit after you coat with any kind of dressing, the salt and acid will help to soften a little more.

Kale shines in so many ways like this Kale and pepitas pesto.

Do you peel the potatoes and how long to roast the potatoes?

Peeling the sweet potatoes or leaving the skin on is your personal preference. But for this recipe, I suggest peeling the potatoes for a better texture.

These sweet potatoes are diced into 1/2 inch cubes and at 425F, it will take 15 to 20 minutes to cook, tossing halfway through.

Using pestle and mortar for grinding

Pestle and mortar

Having a mortar and pestle with a rough texture around the inner bowl is a useful tool to have, if you’ve graduated beyond pre-packaged spices, and you’re ready to grind your own. A larger size mortar is a preference because You can grind any amount you have, but a small mortar works well too. Dried and raw herbs and spices, nuts or seeds when placed in the mortar then crushed and burst with the pestle, releasing their oil and fresh flavor will make a big difference.

using the mortar and pestle to grind is an ideal technique. I use it mostly to grind dried herbs and spices for my preferred texture and more pronounced flavor. Also, it is great to muddle fresh herbs and spices to release their oil and burst their fragrance with the help of coarse salt or peppercorns.

  • Place your ingredients in the mortar and hold it in place with your one hand.
  • With your other hand gripping the pestle comfortably, press the pestle down into the ingredients, and roll against the mortar while applying a firm pressure until you get your prefered consistency.

That said when the kale is treated properly, it will lend a delicate, feathery texture to a salad with a grassy, and peppery bite while those wrinkly edges make for a dramatic presentation especially when you use the curly ones. Combine it with soft and tender roasted sweet potatoes, and dressed it with the highly aromatic and subtle licorice- flavor tarragon vinaigrette, Can you taste it? It is bright, peppery, robust, sweet, and fragrant.

  • 1 tablespoon Peppercorns
  • 1 teaspoon Coarse salt
  • ¼ cup Tarragon leaves, fully packed (about 5 stems)

Instructions
 

  • Set the oven rack at the bottom shelf of the oven and preheat to 425°F. Line a baking sheet with parchment paper.

Prepare the sweet potatoes

  • In a small mixing bowl, combine the coconut oil, honey, and caraway seeds, whisk to combine. Pour into the bowl of cubed sweet potatoes and toss using a spatula until all the sweet potatoes are coated thoroughly. Spread into the prepared baking sheet and into the oven. Roast for 15- 20 minutes tossing halfway through. Sweet potatoes should be tender but not mushy. Take it out from the oven.

Prepare the kale

  • Put all the coarsely chopped kale in a large mixing bowl. Drizzle the olive oil and toss using your clean hands as you give a gentle massage just to soften the kale.

Make the vinaigrette dressing

  • Using pestle and mortar: Add peppercorns, coarse salt, and tarragon into the mortar. Roll the pestle across the salt and peppercorns with a firm grip applying pressure against the mortar until they crush and burst into smaller pieces. Continue rolling while incorporating the tarragon until they are crushed and muddled but leaving some tarragon pieces visible.

Assembly

  • Put the prepared kale, roasted and still warm sweet potatoes, and red onions in a serving bowl. Pour the dressing and toss. Cover with plastic wrap and let it rest in the fridge or countertop for at least 10-30 minutes to develop an extra delicious flavor. Sprinkle the sunflower seeds before serving.

Notes

  • You don’t have pestle and mortar, use the side of your knife to muddle the tarragon as you incorporate freshly ground pepper and fine salt instead.
  • If you’re using Tuscan kale, skip the gentle massage except let it rest for at least 30 minutes. The longer it stays, the vinaigrette dressing will soften the kale leaves.
  • Any dressed leftovers can still hold for the next day, cover and keep in the fridge.
