As far as Fries Are Concerned, Frozen Is Fine

Although it’s possible to make the fries taking a fresh start, it’s much better to begin with frozen fries. The reason is that it will allow you to concentrate on sauce and onions instead. And you won’t have to worry about deep frying.

Also, the conventional animal-style fries consist of shoestring fries. A few months back, I ended up purchasing the golden fries. I thought it was a mistake but it was not. The good thing is that the fries were thicker and held up much better regardless of the type of toppings.

So, what you should do is opt for the fries you like the most whether they are crinkle cut or thin. However, make sure you go for 32 ounces of fries. This will make sure that there will be enough for all of your guests. Also, it’s a great idea to bake them on a pair of baking sheets to ensure they have a lot of room to become crispy.

Many things will be happening at the same time: the caramelized onions will be cooked and the sweet fries will get heated up in the oven. Also, you need to cut them small rather than thinly sliced.

How To Make Animal-Style Fries

It’s important to keep in mind that you need to be patient if you need to cook onions until they are caramelized. If you do it in a hurry, you may end up burning onions. Ideally, you need to wait for at least 45 minutes.

You don’t need to stand around the stove to monitor everything. All you need to do is keep them covered, which will trap enough steam to prevent onions from burning. Just make sure you stir them every couple of minutes. If possible, you can also made the onions a few days ahead. They can also be prepared and frozen so that you don’t have to take a fresh start each time you feel like eating fresh fries.

Now the final touch: It’s a mixture of condiments that you can easily find. In other words, it’s the secret sauce recipe. You can mix mayo if you want creaminess. For tang and sweetness, you can use ketchup. For topping it up, you can use vinegar and mustard.

Once you have prepared the fries, you can pile them on a clean baking sheet. Then you can melt some delicious cheese over the fries and top them up with sauce and onion. Aside from this, you can also serve a few juicy burgers but the fries can be as tasty as hot dogs or grilled cheese.
