Best-Ever Potato Knishes Recipe FAQs
What type of potatoes should I use for the filling?
Absolutely! For the creamiest filling, I recommend using Russet potatoes. They mash beautifully and have the right texture. If you’re looking for something a little creamier, Yukon gold potatoes are a fantastic alternative!
How should I store leftovers?
You should cool the knishes completely before storing. Keep them in an airtight container in the refrigerator for up to 3 days. I often find that they taste even better the next day, as the flavors meld together!
Can I freeze the knishes?
Definitely! To freeze, wrap each cooled knish individually in plastic wrap and then place them in a freezer-safe bag. They can be stored for up to 3 months. When you’re ready to enjoy them, reheat straight from the freezer at 375°F (190°C) for 20-25 minutes until heated through and crispy again.
What if my dough is too sticky?
Very good question! If your dough is too sticky, you can add a little more flour, a tablespoon at a time, until it reaches the desired consistency. Always remember to knead gently to avoid overworking it. A well-prepared dough should be soft but not overly sticky.
Are these knishes suitable for special diets?
You can easily adapt the recipe! For a vegan option, substitute the large egg with 1 tablespoon of flaxseed meal mixed with 3 tablespoons of water to bind the ingredients. Additionally, use vegetable oil instead of schmaltz or butter in the filling to keep it dairy-free. Always be mindful of any allergies your guests may have.
How can I ensure my filling doesn’t leak during baking?
To prevent any leaks, it’s essential to seal your knishes well. After placing the filling, fold the dough over and pinch the edges firmly, ensuring there’s no gap for the filling to escape. Let them rest for about 10 minutes before popping them in the oven, allowing the dough to firm up a bit!
