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.

    Great piping tip! These hold up so well to anything from buttercream to whipped cream. This size is also nice because it's a bit longer, so you don't have to worry about cutting your pastry bag too short.
    I recently used this tip to make a garland design around a cake. This tube came in very handy when I was in need of it to add that extra touch to the cake I was creating.
    Open star #1 pastry tube is very small and detailed. I use it mostly for filling macarons, and it makes a cute little design peak out. The tube is very high quality and has been holding up really good so far. I really do like to.
    The Ateco pastry tube is excellent. It works well with my coupler and is easy to use. I purchased for decorating cupcakes and I have had no issues with it at all.

    The August Thomsen pastry tips are remarkable products, they don't bend like the other brands available online. Easy to clean and always to a great job.
    I love using these smaller tubes as they are more precise. I usually only bake smaller cakes and desserts so these are the one I tend to use.
    I use these a lot so I have several and they do the job they are intended for with ease of use in either bag size I have.
    I strongly recommend this pastry tube. This Ateco 821 3/16" Open Star #1 Pastry Tube (August Thomsen) is perfect to make some borders, rosettes that will complement your desserts.
    Nice tip. We use it for our smaller pastries that we decorate. Makes a smaller star/rosette design so we use less frosting than with a larger tip.
    This Ateco #1 pastry tip is a nice small size tip that is used for small decorations. We use it for piping borders around are sugar cookies to give it that extra wow look!
    Add to your decorating supplies with this open 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 is a nice small pastry tip this is a closed star so you have to use a bit more force but it does look nice
