Question: Do you think the opening is large enough for prepared vinaigrettes that contain finely chopped herbes/onions?
Document: This cruet is great, it doesn't drip and leave a mess all over the counter because it drips back into the bottle. It is pretty enough to leave out on the counter. It pours a finely controllable stream so I use a lot less oil now. Yes, you do have to put your finger on the top or the top part will fall out because it just sits in the cruet (this is why the no drip part works) but I don't find that to be a problem.
It is a very elegant design, and works well with some caveats. The ground glass area of the spout is a great fit, and beats having a silicone (or other) gasket to hold the spout in. The opening of the spout is fairly small, a little over 4 mm. For my salad dressing, I grind spices in a mortar to make sure that they will pass, and I mince soft veggies (like bell pepper) finely for the same reason.
I think they are great. It shire beats looking at ugly bottles, plus it's fun to poor into pans. It gives me the feeling that I'm playing with organic chemistry.
Very useful, a bit pricey but worth it after you've used it. No drips, easy to clean and to use. I think 16 oz is about as small as you want to go unless you want to refill often.
I love my oil containers... no dripping and unique design in terms of what's in kitchen design. Had a few people notice it already where as this was in the lab setting, don't think anyone would of given it a second look. Over all, it does what it states and very light. Have had no issues with it being fragile/breaking as I've read in other reviews.
I'd purchased this larger cruet thinking it would be perfect for olive oil -- which we use a lot of. But it's too large to handle easily and the oil pours out too fast. I prefer refilling my 8-oz cruets more frequently to using the 16-oz version.
I was a bit nervous when ordering about the 16oz cruet being too large to sit out on my small apartment counter, but it fits perfectly and looks fantastic next to my salt and pepper shakers. For those who are a bit hesitant, I've uploaded a picture of the cruet next to a can of vegetables for scale. As for the durability, it looks and feels delicate, but so far it has proven to be very sturdy (even after being bumped against my marble countertops a few times).
Elegant enough to leave on the counter and drip-free for real-world use. Have three (olive oil, canola oil and soya sauce) sitting on our counter and they're functional and beautiful.
I liked mine so much I bought one for my mom too. I keep it right by the stove (but not close enough to affect the oil) and it's so handy to have it there for cooking. The knob doesn't come out of the spout, there are no drips. It's great.
It works fine olive oil and vinegar. I noted one review that commented on using it for liquid soap, which is quite thick. There is a small groove in the spout that allows air to go in as the liquid comes out, and if the liquid is too viscous, air can't get in quickly enough to effectively let the liquid out.
Answer: Vinaigrette yes, onions/minced garlic no.
