Stars and swirlsHow do you make your sugar cookie icing shine? Three things you can do:
1. Add corn syrup (amount below), though this adds just a tiny bit of shine
2. Use a dehydrator on the flooded cookie for 15 minutes. This is the key that really adds the shine! You can use a fan on low overnight, and it will help give a bit of a shine.
3. Airbrushing dried royal icing.
You do not have to spend a lot to get a perfect spray. Here is the cordless I use and love!
I've been asked which food dehydrator I use. I searched, read reviews, and watched YouTube videos on which one was the best. I opted to go ahead and get the 10-rack model. The way my cookie business had boomed, I NEEDED it!
My two cents' worth: if you are planning to have an active sugar cookie business, you will want to get the 10-rack one. This will allow you to grow into it instead of needing another one down the road and spending a lot more money.
The main pros :
-fan in the back, not the top or bottom (makes it more efficient)
-digital temperature settings
-digital time setting
-alarm when it's done
-spacious (10-rack)
-stainless steel (quality)
-fairly quiet
Cons:
-Racks are rectangular in shape instead of square. It's so close that when placing the racks in, you have to turn the rack sometimes to slide them in. Easy remedy. I took a twist tie and twisted it around the front edge of all the shelves. No problem!
I also use Teflon baking sheets over the stainless steel racks, which is the brown you see in my photos here. This assures the cookies' bottoms do not get dry.
I place the cookies with their first coat or color in for 15 minutes on the lowest heat. They are then ready for the next color.

In a cookie business, offering fewer options to customers is better for you.
By the way, here is a page about how to Price for Decorated Sugar Cookies.
Also, the more options there are for customers, the harder it is for them to make a choice.
The busier you are, you will want to freeze cookies ahead of time, whether dough or baked cookies. If you do not have freezer space, then making a ton of different flavors probably is not an option for you.
Instead, what I do is if a customer asks for certain flavors, then I will make what they ask for.

🤗 The above cookie was created using my friend, this PICO projector 💙
I make a double batch of royal icing each time.
1-2 ounces of icing (varies on how much icing you prefer) is, on average, what we flood a 3” cookie with.
The double batch floods about 5 ½ to 6 DZ cookies (66-72)
Here are the ingredients…

"I personally seldom use light corn syrup for the icing. I have never found it to be immensely helpful with the shine (it only provides a little). It's the dehydrator that works for the gorgeous shine on the royal icing. |

Royal icing hates grease!
To be on the safe side, do a quick wipe down of the white vinegar for your bowl and anything coming into contact with the ingredients.

1. Add 1 1/8 c cold water to mixing bowl
Whisk until frothy. There may be some powder not fully incorporated, but it's ok.
4. Add in 2 tsp cream of tartar
5. Add in confectioner's sugar over the cream of tartar
6. Turn the mixer on lowest speed. Scrape down sides once. Whisk again on low for 30 seconds

1. Q: Will this recipe hold up to piping stiff things like roses?
A: Yes! Here are a few examples:

Thick consistency ruffles2. Q: Can I freeze royal icing?
A: Absolutely. It can be beneficial for you in more than one way.
Just make sure you keep it air-tight.
When you remove it from the freezer, if it's stored in a bowl with a lid, it should only take about 30 minutes (for 2 cups) to thaw. If it's stored in a piping bag, it'll thaw in about 10 to 15 minutes, depending on how warm your kitchen is.
I store mine in those glass bowls with plastic lids sold at Dollar Tree. Very handy!
3. Q: Why do I get so many bubbles when piping/flooding?
A: As you already guessed, it is trapped air. When making sugar cookie icing, it is a must to place your mixer at the lowest speed possible. Every mixer is different, but shoot for about 5 minutes total mixing time.
Another reason is adding too much water at one time when mixing colors. Go for a couple of drops at a time or try a spray bottle designated for this purpose.
A good remedy is to mix your colors and let them set ideally for 24 hours or overnight. This allows the bubbles to rise to the top.
4. Q: My icing is way too thin. Should I throw it out?
A: Not at all! Simply sift in more confectioners'/powdered sugar to reach your ideal consistency.
5. Q: I have a few different colors left over. How can I use it instead of tossing it?
A: Here's a nifty idea. Mix all the colors with the confectioner's sugar to make it very stiff, like a thick putty. You can make 'rocks' out of this or even figures. Roll it into a ball and pinch a little off. Form it by squeezing it between your fingers into odd shapes.
