Salt to Meat Ratio Depending on who you talk to you or which web site you visit, you'll get a different answer regarding how much salt to add to meat. Based on research and my own experience, around 3/4 of a teaspoon of table salt or sea salt per pound of meat works well in most situations. I have also used as much as 1 teaspoon per pound depending on the recipe. You really need to understand your likes and your recipe to determine the best amount of salt. It's also important to factor in the type and brand of salt. Most table and sea salt are approximately the same. For example, table salt is fine so it is tightly packed while kosher salt tends to have irregular crystal shapes leading to less sodium per measurement. Even among the varieties of kosher salt there are vast differences so be warned!
In the early 1950s, the tri-tip cut from the bottom sirloin was often used for stews, sliced into steaks or ground. Not until Bob Shutz, a butcher in Santa Maria, experimented with this cut did it gain popularity. Now there are so many variations of the Santa Maria dry rub, it's hard to determine the original recipe but I always say variety is the spice of life The key of any good Santa Maria rub is salt, pepper and granulated garlic. What you add in addition to this foundational mixture is really up to your own personal taste buds.
I like to add dried rosemary to my Santa Maria rub. It's my favorite aromatic herb. In order to get it powdered, I use my hand-dandy NutriBullet. A Magic Bullet or any Spice Grinder or Coffee Grinder will work well also. I add whole black pepper corns along with the rosemary cause it's too difficult to grind that much pepper that finely. After a minute, I add the rest of the spices and pulse the bullet to mix them.
Generously rub your tri-tip all over with the Santa Maria dry rub. That's why they call it a rub, cause your supposed to massage or rub it into the meat for a few minutes. Don't be afraid to make a mess, that's how you know you are doing it right... lol. Two 2 pound tri-tips should just fit into a one gallon ziploc bag. Store the meat overnight so the flavors can penetrate into the meat.
Grill that slab of meat on direct heat on your outdoor grill. Tri-tip is best cooked hard and fast. Not too hard that you scorch the outside but enough that you get the perfect sear on the outside along with perfect doneness on the inside. It takes practice but tri-tip is pretty forgiving because it is so thick. A tri-tip is also thick enough to use a thermometer but it just gets in the way when you flip. I prefer not to poke my beef multiple times, letting the juices out so I prefer the touch method. If you have barbecued enough meat, you can touch it quickly with your finger or a grilling tool and instantly tell the internal temperature based on the way the meat reacts to your force. You want the tri-tip to just start firming up to get medium-rare. Too firm and it is overcooked. Too much give and it is raw in the middle.
Let your tri-tip sit for 10 minutes on the cutting board before slicing so the juices can absorb back into the meat. Cutting the beef right off the grill will result in all your delicious juices spilling out onto the cutting board.
