How to cook Potato tarts

Step 1

Potato tarts - FAQ About Ingredients, Baking Time and Storage

Yes, you can substitute instant yeast for dry yeast. Use the same quantity but skip the activation step (Step 1) and mix it directly with the flour. The dough may rise faster, so keep an eye on it.
To make this vegetarian, replace the chicken egg in the dough and filling with a flax egg (1 tbsp ground flaxseed + 3 tbsp water per egg) or a commercial egg replacer. Ensure the mashed potatoes are also prepared without animal-based ingredients.
Yes, the dough can be refrigerated overnight after kneading (Step 4). Let it come to room temperature and rise slightly before shaping. Alternatively, freeze the dough for up to 1 month; thaw in the fridge before using.
Store cooled tarts in an airtight container in the fridge for up to 3 days. Reheat in the oven at 160°C (320°F) for 10 minutes to restore crispness. Avoid microwaving, as it can make them soggy.
Yes, freeze fully cooled tarts on a tray before transferring to a freezer bag for up to 2 months. Reheat from frozen in a 180°C (350°F) oven for 15-20 minutes until warmed through.
Try sweet potato mash, sautéed mushrooms, or ricotta cheese mixed with herbs. Adjust seasoning as needed. Ensure fillings are cooled and thick to prevent soggy dough.
For smaller tarts, divide the dough into more balls (e.g., 12 instead of 8) and reduce baking time by 5-10 minutes. For larger tarts, increase baking time by 5-10 minutes and monitor for doneness.
Check yeast freshness—expired yeast won’t activate. Ensure the water is warm (not hot) and the dough rests in a draft-free, warm spot. Cold environments slow rising.
Yes, but use a 1:1 gluten-free flour blend with xanthan gum for structure. The dough may be stickier; wet your hands to handle it. Expect a denser texture.
