The Colour Mill #1M Piping Tip is the go-to large open star tip for cupcake rosettes, layer cake borders, and meringue piping. Made from professional food-grade stainless steel, it is compatible with all piping bags. Clean results, defined ridges, and a shape that stays stable over time.
Technical specifications
- Brand: Colour Mill (Australia)
- Reference: #1M — large open star
- Material: professional food-grade stainless steel — does not deform under pressure
- Compatibility: all disposable and reusable piping bags, with or without a coupler
- Care: dishwasher-safe and suitable for hand washing
Applications — what you can make with the #1M
- Cupcake rosettes: the shop's signature piping technique — spiral from the center outward, with continuous pressure for a perfect result
- Layer cake borders: regular ruffles around the edge or a crown of rosettes on top
- Number cakes: filling with aligned rosettes for biscuit numbers and letters
- Italian meringue: rosettes for lemon meringue pies and Christmas logs
- Pavlovas: a crown of stabilized whipped cream around the meringue base
- Cream puffs: piped on top in a ridged dome shape
Ideal consistency: buttercream that is too soft will collapse and lose its ridges; if it is too firm, it will clog the opening. Aim for a texture that holds a ribbon on the spatula. For whipped cream or whipped ganache: add 2 g of mascarpone or gelatin per 100 g of cream to keep the pattern in place for several hours.
Instructions — perfect cupcake rosette
- Setup: insert the tip into the piping bag, with the opening facing the point. Cut the bag level with the base of the tip — neither too wide nor too tight.
- Filling: fill the bag two-thirds full and remove air by pressing toward the tip.
- Piping the rosette: hold the bag vertically 1 cm above the surface. Start in the center and spiral outward with constant pressure. Stop squeezing before lifting the bag.
- Finishing: add a sugar pearl, edible flower, or piece of dried fruit to the center of each rosette.
- Cleaning: wash immediately after use in hot, soapy water. Dishwasher-safe.

Frequently asked questions
What is the difference between the #1M and the #2D?
The #1M is an open star tip — more numerous, finer ridges and a more textured rosette. The #2D is a closed star tip — wider ridges and a fuller appearance. Both make beautiful rosettes; choose according to the look you want.
Do I need a coupler?
No for standard piping bags — the tip fits directly inside. Use a coupler if you want to change tips without emptying the bag.
Is it dishwasher-safe?
Yes. Rinse quickly after use to prevent cream from drying in the ridges, then wash in the dishwasher or by hand.
