If I don't buy the fresh masa dough or make the fresh masa dough, I generally use the instant method. It's called... Instant Corn Masa Flour for tortillas. I don't know if I'll ever use it again after making the fresh from the Fresh Corn Masa this week! However, in fairness, I will probably still have busy weeks and make it using masa harina (corn flour).
4lb bag makes a very large quantity of tortillas...so it saves us a lot of money. Honestly though, the taste of homemade corn tortillas is absolute heaven. I have never once had a corn tortilla in a restaurant or off a grocery store shelf to match the tenderness of a homemade corn tortilla...ever. It usually takes about 15-20 minutes to make 16 tortillas from scratch. I do that while the meat for the tacos is cooking. It's quick dinner.
This recipe for the corn tortillas is from Doña Masita. MASECA - Tortillas.
For the Dough:
In a bowl mix 2 cups loose instant masa, 1 1/4 cup water and 1/4 tsp salt until it is all incorporated and a smooth dough is formed which doesn’t stick to your hands.
If the dough feels dry, add teaspoons of water (one by one). Once the dough is ready, cover with a wet towel so that it does not dry out.
Divide the dough into 16 equal portions and form little balls.
Cover with a damp towel to keep moist.
Flatten each ball between two sheets of wax paper, using a press for tortillas and start making the tortillas. You can use parchment paper or heavy plastic wrap as well. You don't have to use a Tortilla Press , but it takes a lot less time and energy to use one. I highly recommended it. 
Hello you lucky dough ball. Brace yourselves...
Once the tortilla is ready, cook on a hot griddle for 1 minute each side, or until the tortilla fills with air. Look how cool they look...
Again, one minute on each side is all it takes to cook them. On a large griddle I can get eight at a time going!
I keep the tortillas in a nice covered tortilla warmer until we're ready to eat.
If you decide to fry them to make chips, be prepared to let them cool completely first. Also, they make amazing enchiladas, tostada shells, taco shells, quesedillas...you name it. We went ahead and used some fresh salsa verde.
With home grown cilantro...also still growing nicely in the garden. Be jealous. I walked out barefoot and gleaned some from my cilantro forest. Arizona is amazing for year round gardening. I'll be calling you in July when I'm crying in my 200 degree kitchen.
Cheese is optional...but always loved. Just like me.
There you go. Make yourself some corn tortillas!
