How to Pipe a Rose with Buttercream Frosting

How to Pipe a Rose with Buttercream Frosting

Use these simple steps to professionally add a buttercream rose. You'll need a spatula, rose tips, a leaf tip, couplers, a flower nail, a rubber spatula, and piping bags. Begin by squeezing cream onto the flower nail in a circular motion, creating a lump with a tip on it. To create the layers of a rose, squeeze cream in an short arch motion and continue rotating the rose until you have the desired amount of layers, or petals.

Ateco Piping Bags, Short Spatulas and Pastry Tubes

Ateco Piping Bags, Short Spatulas and Pastry Tubes

Hi, this is Julie Bashore from the Sugar Arts Institute. Let’s have fun with some of the Ateco piping tips. Working with their disposable piping bags that come on a roll, they tear off really easily, I like to work with the smaller 12” bags but they also have 18”. Working with a coupler, remove the nut from the base of the coupler and place the base in the bag as tightly as you possibly can. Working with a pair of scissors, above the screw marks, just cut the edge of the bag and remove that. And then you’re going to choose the piping tube that you’d like to work with, place it on the top of the coupler, and screw it down firmly. This is a piping bag stand; it’s very convenient, especially if you’re piping alone or you don’t want to interrupt anyone to fill the bags, it holds the bags really well and you can slip your icing in there. This is the short-ended Ateco spatula which is quite wide so it’s really convenient for picking up the buttercream. Pull the bag up, place it on the table, and spread the buttercream down to the end. And then of course it’s important not to forget to burp the bag. This piping tip that I’m using is a ruffling pipe piping tip, and it’s absolutely amazing how quickly it works. Have a look, come in close. Doesn’t that give an awesome ruffle? Let’s work with another tip. This is the shell tip; don’t forget to burp your bag. This is great for a border; in fact, I sometimes use it on the edge of my ruffle. It gives a really nice shell design. The tip itself is curved so it gives a nice puffy shell appearance to it. Ateco has a new set that they’ve brought out: polycarbonate plastic piping tips, they are large tips, very strong and very precise in the edging. This one is a basket weave design; it really makes an awesome border. Place the bag over the holder, again, don’t forget to push the butter cream all the way to the edge and burp the bag. It has two edges, a flat edge and a scalloped edge so this makes a great ribbon design; you can also wiggle it or make just a ribbon and also wiggle this. Flip it over and wiggle. Great for basket weave.

    These pastry bags are very economical and work very well for piping ice cream. We use them to pipette cream onto our sandwich waffle wafers and they are great!

    from McFen Custard LLC Posted on

    They're clear, they're plastic, they're disposable. You dont need much more in a disposable pastry bag. You can wash them and reuse them about a dozen times before you find them to be completely unusable anymore.

    I like this bigger size pipping bag. It very sturdy and it poly. This bag doesn't break and you can fill it up with lot of creme, custard, fruit filling and buttercream. It a big bag and it holds very well!

    from Zetta Marie's Patisserie Posted on

    We should have switched over to these poly bags from the old fashioned canvas ones a long time ago. More sanitary, no labor to clean and no space taken up drying.

    from Creativa Posted on

    These bags are perfect for all my decorating needs. They are strong, durable and just the right size. I will never buy a different bag again.

    from Stealth Management Posted on

    Perfect piping bags. They are strong, and hold up well to different fillings. The length is perfect for our needs. We would purchase them again.

    from Palmer's Sweetery & Cafe Posted on

    These pastry bags are such a convenient way to decorate baked goods. They are sturdy and hold up to any frosting or filling, get the job done and throw out the bag!

    from Sedgwick deli and grocery store Posted on

    Nice large, strong durable pastry bags. No issues with rips or tears. Hold a lot of frosting for our cup cakes. Disposable so no more washing bags.

    from Russ' Sub Shack Posted on

    These are awesome! Well made and easy to use! They are thick and don't rip like others we've used. We will continue to use these!

    from Mr Baker Man Posted on

    I love how these are on a roll and easily tear apart. We used them for a student competition. They are a little large but it does keep frosting at bay when students are learning to pipe their frosting.

    from Whitehall School District Posted on

    Bought other brand that costs twice as expensive then this piping bag and there were no difference. Strong and clear to see what's in the bag.

    from HOME USE Posted on

    Very nice, large pastry bag! Has a tacky feel to the outside for easier gripping. This comes in handy when filling cupcakes, and or cakes!

    from The One Butt Bakery Posted on

    I was so excited to have found these! I have the 18" bags, but they seem to run out way too quickly for me cakes. These allow me to save time and Hassle of refilling as often.

    from Everything Iced Cupcakes & More Posted on

    Good product, nice sized bags and a good, heavy duty plastic. I've had problems with plastic bags in the past being too thin for higher viscosity ingredients, but these bags are tough!

    from Proof Artisan Distillers Posted on

    When icing cakes in our business, we use these bags. The sides don't split and the price is the best we've found. Our employees love the amount of icing each bag holds.

    Posted on

    Use the pastry bags all the time. Love them for both icing cupcake and filling cupcake molds without any mess. They are really easy to grab out of the box.Just the right size for large amount of icing and you can just throw away when done. No cleanup, will order again!

    from Our Store Posted on

    These bags worked just fine and held under stiffer buttercream. I had no issues without using a coupler. I would highly recommend these bags. Yes

    from Cheryl Lantz Posted on

    These bags are perfect for big jobs.. No need to refill the bag multiple times because it holds a large amount of frosting and the bags do not split open.
