I wanted to share this recipe as part of a way to share how to make restaurant-style food at home with ease. I have always loved clam chowder as a kid and when my kids were old enough to have it they had their first taste of clam chowder on Fishermans Wharf in San Francisco and they have been in love with it ever since. Well, since moving away from California, we have found that when you have those cravings for chowder, it’s not just a train ride away.
In fact, my kids kept asking for clam chowder, and every time we went home to California for a visit the Wharf was one of our first stops. We had chowder when we first arrived and chowder on our way out.
Where we lived on the east coast did not have easy access to good chowder, so we decided to venture into making it at home. Again the goal is to learn how to cook things you love. Because in time, our kids will move out and have their own homes and I know them well enough to know, they would probably try to have clam chowder every week!
You want to choose good ingredients and make sure that you can make food quickly, easily, and enjoy the process of doing it.

FAQ’s & Tips
I do not like to add my clams in too early, it makes them firm. But some people like them that way, if you want yours to be on the firmer side add them in prior to setting the pressure cooker on.
How do you thicken clam chowder?
Add a tablespoon of corn starch to about ¼ of cream and mix. Add to the pot and stir in while adding. The chowder will slowly thicken as you whisk in the corn starch mix
Is clam chowder better the next day?
YES! It tastes amazing when you first make it, but when you let it sit overnight it seems to just get better. We generally don’t make it to the next day of eating from this recipe. We love clam chowder so much
Should I rinse canned clams?
I do not recommend rinsing because you are going to want to keep all the flavor on the clams.
Do you drain canned clams?
Yes, you should drain them only to be able to add the clams at the end to keep them nice and tender.
