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.

    Ateco provides a quality product when it comes to this piping tube. The closed star makes for a nice design on cakes with its ability to allow for very detailed work.
    Closed star #2 pastry tube is one of the smaller pastry tubes. I like to use it for decorating cakes or cupcakes sometimes even cookies. It makes rather small cute design which is pretty detailed. The quality of the pastry tube is very nice as well
    The tip of this pastry tube measures 1/4" wide and the tube is constructed of stainless steel. This pastry tube is great for decorating cakes, cupcakes, and other desserts. The closed star shape pastry tube is another style pastry tube we own. This pastry tube is made by Ateco, a quality manufacturer of pastry bags and tools.
    I like these size particularly for cup cakes. They are not too strong but not to big to make intricate designs and not overwhelm the cupcake.
    Ateco 842 1/4" Closed Star #2 Pastry Tube (August Thomsen) is a good filling utensil that can both outline and fill in so it's versatile.
    This is a great pastry tube to have in your collection! This closed star #2 is perfect for that attention to detail work. The icing is very thin and great for detailing flowers.
    The Ateco 842 1/4" Closed Star #2 Pastry Tube (August Thomsen) is great. I really like the design. Perfect for cupcakes. The quality is very good and the price is reasonable. This is definitely a great value.
    i used this tip when I did a paw patrol cake for my nephew, it worked perfect to give kinda of grass effect around the cake. i held the bag up right, gave it a light squeeze, and then twisted while lifting the bag away
    The Ateco closed star tips have one of the best looks for piping borders, but keep in mind if your icing has a good thick consistency it will require a bit more force to pipe then a regular open star tip.
    Add to your decorating supplies with this #2 closed star Tip. Easily add a unique design with a little creativity. This tip is made of high quality stainless steel and as long as you follow simple washing techniques, it will last you a long time.
    This one has a small opening. It's good for piping those stars to fill in a design and so much more. It uses a medium size coupler.
    Ateco 842 1/4" Closed Star #2 Pastry Tube (August Thomsen) if you need a thin star shape pattern in your pastry or icing you can use this tube
    Love these tips for all my cakes big or small. I use daily and they wash well too. Will definitely order again price is right
    Great tip for doing large detail work or covering small cakes with nice deeply grooved swirls. Good metal construction, solid and clean when piping. Get a coupler to make your life easier when changing tips!
    I love the closed star tip for making rose swirls on my cakes. They turn out so pretty, and it's very easy to do. This tip is sturdy and has not bent at all.
    I bought many Ateco tips from webstraunt.com and this closed star tip is wonderful like all of them. It is on the smaller side so you can make little flowers, roses. Great for mini cupcake decorations. The flowers come out smooth and perfect. made of quality stainless steel.
    The Ateco 842 closed star tip is very small, I could characterize it more a decorators tip than a bakers tip. Nonetheless, it works great at piping small royal icing cherry blossoms! Neat tip!
