These littleneck clams are so quick, easy, and delicious. They cook in under 10 minutes! The broth is made without citrus and is non-alcoholic.
Make sure your clams are stored in a cool place and are able to breathe. Scrub clams under water and place into a large bowl with ice cold water. Discard any with large chips or that do not close with a little "tap" on your counter. Allow them to sit for 15-20 minutes to expel any extra grit/sand. Carefully remove each one (do not dump) and place on a towel.
While clams are sitting in water, prepare a large, heavy bottomed dutch oven or pot with cover by melting butter and olive oil over medium heat. Add shallots and saute for about 1 minute. Then add garlic and saute a minute longer.
Add broth and bring to a simmer. Then carefully add in clams. Cover the pot with a lid and simmer for 7-10 minutes. Clams will open when they're done. If one does not open, give it a little longer to simmer. Throw out if it continues to not open.
Remove clams from the pot with a slotted spoon and place into a big bowl. Meanwhile turn the heat up a little bit to get a strong simmer going. Simmer the broth an extra 4 minutes or so, until it's reduced enough to your liking. Pour the reduced broth over the clams.
Top with fresh herbs and vinegar, which will give it the acidity you miss from wine or citrus. DO NOT ADD SALT - the clams should be salty enough as is. Serve immediately. Bread is a really great idea here (unless doing a paleo or whole30 option) to sop up all that butter broth!
