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.

Ateco 400 Details

This Ateco 400 2-piece standard plastic coupler allows you to interchange small / standard-sized piping tips with absolute ease! Even though all reusable bags can accept small decorating tips without a coupler, this convenient item enables you to swap out piping tips without having to empty the contents of your decorating bag, which saves you time and labor.

That said, to use this coupler properly, simply trim your reusable bag before use! However, since canvas bags with a sewed seam cannot be trimmed, they are not compatible with this item. In addition, ridged edges on the ring allow you to easily assemble the coupler to the base with minimal effort. This coupler works best with standard-sized piping tips that have a 11/16" bottom diameter. Ideal for bakeries, cake decorators, coffee shops, and anywhere else you need to decorate baked goods, this plastic coupler will get the job done!

Bringing you innovation and quality for over 100 years, Ateco, an August Thomsen brand, has been internationally known in the industry for creating baking tools of superior craftsmanship and design. By continually improving on tools, materials, and packaging, Ateco is dedicated to providing professional bakers with the kitchen essentials they need to succeed in an ever-evolving industry!

    In providing easy interchangeability for decorating tips, these couplers save a decent amount of time and equipment usage and free up workspace as well. They pair perfectly with Ateco's Plastic Coated Pastry Bags - a small investment with a huge payoff!
    Easy to use, easy to clean, very worth it for the very low price. I use it with the other ateco branded piping tips and have not had any issues
    Love these couplers. They are heavy duty and hold the tips perfectly. Makes switching from tip to tip so much easier. Will definitely purchase again.
    this standard plastic coupler worked well it was a little small for most of my tips to fit put came in handy when I needed more than one piping tip
    We use this coupler with the the Ateco 14" poly bag and its perfect for quickly switching between tips. The plastic used on these feels nice and solid. We've experienced in the past that other brands just do not feel as solid and arent as secure. These have been the best we've used thus far!
    Very economical and sturdy. If the pastry bag bursts, it's usually b/c i cut too much of the bag off, not because the couple was faulty.
    I am a big fan of using a coupler for decorating baked goods with icing. These allow you to change tips effortlessly which saves so much time.
    These couples are simple and easy to use. They do stain a little bit if you use with reds, blacks, and purples but that's to be expected when you leave in contact for an extended period. They are easy to clean and priced great!
    STRONG plastic coupler, much, much better than the "other" products out there! Holds up greatly and does it's job perfectly, love the quality and will be ordering more!
    I was doing a cookie demonstration at our local school and I needed extra couplers for the students to use. These were very affordable and of good quality. I typically purchase the Wilton brand, but I will definitely be switching to Ateco.
    This plastic coupler was very helpful. Since using it I have not over or under cut my piping bags and all the piping tips stay put through the icing process.
    These couplers are a great product to have in a kitchen where baking is done. They are sturdy, twist easily around the tips and make for easy cleanup.
    I live these couplers! They come especially in handy when decorating cookies and cakes. They are easy to clean and fit all of the smaller tips.
    Works great - tightens easily & secures standard cake decorating tips well. I use these with disposable decorating bags and have no complaints. They clean easily in warm soapy water.
    This standard coupler is the smallest size ateco makes and is necessary for using and interchanging smaller tips. It is very easy to use but also easy to lose one of the pieces
    for the price i cant complain about these tips. they screw together well and as long as the bag isnt too thin they hold very well.
    Great design for all types of decorating bags. They attach well with no issues. They hold all different types of tips from different makers with no slippage.
    These are standard couplers for cake decorating bags. They are very sturdy and wash well in the dishwasher. We have many of these and can't decorate cakes without them.
    What can I say? They work well and do what they're supposed to. Now, if I could only get the staff to not loose them I would be happy. They are good quality and have been used many of times without any issues. I would buy these again.
    The only coupler we use and order are these ones! Ateco has quickly become our favorite brand to use. The merchandise is made very well and lasts a long time. We go through couplers often so this is a great deal and lasts us a while!
