Combine the broth and the crushed saffron threads in a 1 quart pot and bring to a simmer.
Meanwhile, remove the tough ends of the asparagus, wash, and cut the stalks on the diagonal into ½ inch pieces reserving 1 ½ inches of the tip.
When liquid is simmering drop in the asparagus stalk pieces and blanch for 2 minutes until bright green and slightly tender. Remove with a slotted spoon to a small glass bowl. Add the tips to the simmering broth and cook for 1 minute. Remove from broth and set aside. Keep broth warm while you prepare the barley.
Heat a three quart saucepan over high heat for 10 seconds. Add the extra virgin olive oil and heat for 10 seconds. Add the onion and garlic and reduce heat to medium. Sauté mixture until onions are slightly golden but do not let garlic burn.
Add the barley and stir to coat with the onion mixture and oil.
Add the wine and stir constantly until the wine is absorbed. Add all of the simmering broth, stir, and then cover and reduce heat to low. Stir the barley mixture every 5 minutes or so to prevent sticking and burning. If all the liquid has been absorbed and the barley appears too hard and/or dry, then add another ¼ cup of water and cook for another 5 minutes. The barley will be firm, but tender after 30-35 minutes.
Remove the pot from the heat and stir in the salt, pepper and lemon zest until well combined.
Gently combine the grated cheese into the mixture and when evenly distributed and melted add the almonds and the reserved asparagus pieces (MINUS 5 asparagus tips for garnish).
Immediately serve the barley risotto in a nice dish garnished with the reserved tablespoon of almonds and the 5 remaining asparagus tips.
