Recently been making Camemberts using standard 4-1/4" / 11.0 cm inside diameter hoops and ladling curds into hoops using standard cheapo smallish kitchen ladle.
So like the artisan cheesemakers in France I ordered myself a larger stainless steel ladle hoping it was the same diameter as the hoops, but with the bonus of a built-in strainer for reduced whey transfer to the hoops.
Just got it today, great quality, heavy duty, when held level it just fits 8 fluid ounces/225 ml, but it's not round, it's oval!! And they just dropped the price from USD15 to 12!!
Anyway expect it will still work well. Unit's cup outside dimensions are 4-3/4" / 12.0 cm x 3-3/8" / 8.5 cm. Total length is 13.5" / 34.5 cm so not a very long handle for size of cup. Will reply here how well works after next batch.
