Got this for making omelets
Color: Silver 8Oz (250ml), Color: Silver 8Oz (250ml)
I bought this pitcher/mug mainly for beating eggs when making omelets. It’s a bit smaller than I expected, but it works well for single or double omelets, especially since I usually mix in a few extra ingredients. It did not come with a stirrer, may be it is not included with the 8 Oz mug. I had been using a plastic container before, and this stainless‑steel mug definitely makes a louder noise while stirring, but that’s expected with metal. The mug itself feels well made. Time will tell whether the stainless steel holds up without rusting and whether the handle weld stays strong. The handle is comfortable to grip, and the opening is wide enough to clean with a scour pad. I haven’t put it in the dishwasher yet, but the description says it’s dishwasher‑safe.

Standard, good deal!
The frother cup is great! It is just as I remember them from my days as a barista. It seems to be standard size, and fits well with my Breville. I definitely need some lessons on steaming milk though!
