The Inspiration

On Dine Your Sign, host Siobhan Detkavich creates recipes inspired by the unique characteristics associated with each zodiac sign. Virgo, ruled by Mercury and connected to the Earth element, values thoughtfulness, nourishment, and attention to detail. These qualities are reflected beautifully in this comforting knish recipe.

Knishes have long been cherished in Eastern European and Jewish culinary traditions. Traditionally filled with potatoes, vegetables, or meat, they are celebrated for their hearty nature and satisfying texture. This version introduces nutrient-rich spinach and earthy tur

Ingredients

• 1 ½ pounds (680 g) Russet potatoes, peeled, cut into large chunks
• Olive oil, for sauté
• 2 onions, finely diced
• 4 garlic cloves, minced
• 1-pound (454 g) baby spinach
• 1 tablespoon (15 ml) ground turmeric
• Salt and pepper
• ½ cup (120 ml) sour cream, room temperature
• ¼ cup (60 ml) butter, melted
• 2 x 17-ounce (482 g) package puff pastry, thawed if frozen
• 2 eggs, beaten

Method

• Preheat oven to 375 F (190 C)
• Place the potatoes in a large pot of salted water and bring to a boil over medium-high heat. Cook the potatoes until tender, 15-20 minutes.
• Meanwhile, heat the olive oil in a skillet over medium heat, add the onion and garlic and cook until softened and aromatic, 3-4 minutes.
• Add the baby spinach and cook until just wilted, tossing often, 1-2 minutes
• Remove spinach, onions and garlic from heat.
• In a small bowl, mix sour cream and turmeric until uniform in color.
• Drain the potatoes, then when just cool enough to handle, pass through a potato ricer back into the still-warm pot. Add melted butter, spinach, onion-garlic mixture, and turmeric-sour cream. Season with salt and pepper and mix well
• Allow the mixture to cool to room temperature.
• Roll the dough out into a ¼ inch (6 mm) thick rectangle. Cut the dough into 3 to 4-inch (7.5 – 10 cm) squares.
• Place roughly 2-3 tablespoons (30-45 ml) of filling per square. Brush the edges of the squares with beaten egg. Fold the four corners in to meet in the middle, like an envelope, pinching the edges closed.
• Place the knishes on a parchment-lined baking tray and brush with the remaining beaten egg.
• Bake for 25-30 minutes, turning the pan halfway through cooking, until golden-brown and cooked through.
• Allow the knishes to cool for 5-10 minutes, then serve.

Serving Suggestions

For lunch or a light dinner, pair the knishes with a crisp green salad dressed in a simple vinaigrette. The freshness of the greens balances the rich pastry and creamy filling beautifully.

These knishes also complement soups exceptionally well. A bowl of vegetable soup, tomato soup, or creamy celery root soup creates a comforting and satisfying meal that highlights the earthy flavours within the filling.

For entertaining, arrange the knishes on a serving platter with small bowls of sour cream, herbed yogurt sauce, or grainy mustard. These accompaniments add extra flavour while allowing guests to customize each bite.
