If you’re looking to mix things up a bit, there are plenty of substitutions and variations you can try with this recipe for Leftover Potato Cakes (Irish Style). Here are a few ideas to get you started:

– Roasted Garlic and Carrot: To add a little more flavor and texture to your potato cakes, consider mixing in some roasted garlic and grated carrot. Simply roast a few whole cloves of garlic until they’re soft and fragrant, then mash them into the potatoes along with the grated carrot. This will give your potato cakes a unique sweetness and depth of flavor.

– Cheese: If you’re a cheese lover, try adding some grated cheese to your potato cakes for an extra burst of flavor. Cheddar or Parmesan are both great options, but feel free to experiment with different varieties to find your favorite.

– Plain Flour vs Self-Rising Flour: This recipe calls for plain flour, but you can also use self-rising flour if that’s what you have on hand. Just remember to omit the baking powder if you do so.

– Egg: The egg in this recipe acts as a binding agent to hold the potato cakes together. If you don’t have an egg on hand, you can substitute it with 1/4 cup of unsweetened applesauce or mashed banana.

– Boxty Irish Potato Pancakes: If you’re looking for a slightly different take on these potato cakes, consider trying out the traditional Irish dish known as boxty. Boxty is made from mashed potatoes and grated raw potato, which gives the pancakes a unique texture and flavor. Try swapping out half of the mashed potatoes in this recipe for grated raw potato and see how the results compare.

Remember, cooking is all about experimenting and finding what works best for you. Don’t be afraid to try out your own substitutions and variations to make these Leftover Potato Cakes (Irish Style) truly your own.

It is always a good idea to have some leftover potato cakes on hand. These cakes can be easily made in advance and stored for later use. After you have cooked the potato cakes, allow them to cool completely before storing them. You can wrap them in a plastic wrap or store them in an air-tight container.

Now that you’ve got the recipe how-to for these delicious Irish-style potato cakes, let me share some tips and tricks to ensure that they come out perfectly every time.

1. Use leftover mashed potatoes: The texture of these potato cakes comes out best when using leftover mashed potatoes that are cold and thick. Freshly-made mashed potatoes can be too watery and may not hold together well when forming the cakes.

2. Don’t overmix the ingredients: When mixing the mashed potatoes with flour and egg, be careful not to overmix the ingredients. Overmixing can result in a tough and dense texture, so mix until just combined.

3. Drain any excess moisture: If your mashed potatoes are on the wetter side, use a paper towel or cheesecloth to squeeze out any excess moisture. This will help the potato cakes hold together better when frying.

4. Flatten them evenly: When forming the potato cakes, make sure to press them down evenly so that they cook evenly as well. Use a measuring cup or your hands to shape them into uniform patties.

5. Fry in small batches: To prevent overcrowding the pan, fry the potato cakes in small batches. This will ensure that they cook evenly on each side and get nice and crispy on the outside.

6. Choose your oil wisely: Use an oil with a high smoke point, such as canola or vegetable oil, to prevent burning and smoking in the pan.

7. Try different variations: Don’t be afraid to experiment with different variations of this recipe! Add in some grated cheese, roasted garlic, or shredded carrots for extra flavor and texture.

By following these tips and tricks, you’ll have perfectly crispy and flavorful Irish-style potato cakes every time!
