Got it, let's tackle this article on how to make yogurt. First, I need to hit 600-900 words, use the context given, natural headings, no AI mention, only allowed HTML tags. First, the main heading should be h2? Wait no, wait the user said natural headings. Wait, first the title? Wait no, let's start with an h2 for the main intro? Wait no, wait let's structure it properly. First, opening: Maybe start with an h2 that's the main topic? Wait no, wait let's see. First, maybe an intro paragraph talking about how homemade yogurt is easy, cheaper than store-bought, you can control ingredients, no weird additives. Mention that once you make your first batch, you can save some as a starter for future batches, that's from the context. Also, mention Greek yogurt option, that's the "why buy greek" point. Wait first, let's outline the headings: 1. First h2: Why Make Homemade Yogurt? That covers the benefits, no additives, cost, control over sweetness, tanginess, also mention that you can make Greek yogurt at home without paying the premium, that hits the "why buy greek" context. Also mention the starter culture thing here? Wait no, maybe later. Wait then next h2: What You’ll Need to Make Yogurt. List the ingredients and equipment. Ingredients: milk (whole, 2%, whatever, maybe note that ultra-pasteurized works too? Wait no, avoid unsupported claims, just say most types work, avoid ultra-high temperature? Wait no, better to say: 4 cups (1 liter) of milk of your choice (whole, 2%, or even non-dairy alternatives like oat or soy work for vegan options), 2 tablespoons of plain unsweetened yogurt with active live cultures (store-bought or saved from a previous batch, that's the starter part). Equipment: a large heavy-bottomed pot, a candy or instant-read thermometer, a whisk, a clean glass jar with a lid, a warm spot for incubation (like an oven with the light on, or a yogurt maker if you have one, that's practical). Wait also, maybe mention that if you want Greek yogurt, you just need a cheesecloth or fine mesh strainer, that hits the Greek part. Then next h2: Step-by-Step Homemade Yogurt Recipe. That's the "how to make yogurt" core. Let's break the steps down clearly, no jargon. Step 1: Heat the milk. Pour milk into the pot, heat over medium heat, stir occasionally to prevent scorching, heat to 180°F (82°C). Wait why? Because it denatures the proteins to make a thicker yogurt, that's a factual point, no unsupported claim. Then step 2: Cool the milk. Let it cool to 110-115°F (43-46°C), that's the ideal temperature for the cultures, too hot will kill them, too cold won't activate. Step 3: Inoculate the milk. Take a small amount of the warm milk, mix it with your 2 tablespoons of starter yogurt in a small bowl until smooth, then pour that mixture back into the pot of warm milk, stir gently to combine. Step 4: Incubate the yogurt. Pour the mixture into your clean glass jar, cover with the lid, place it in your warm spot (like an oven with the light on, which keeps it around 105°F, perfect) for 6-12 hours. The longer you leave it, the tangier it will get. Step 5: Chill and set. Once incubation is done, put the jar in the fridge for at least 4 hours, it will thicken up more as it chills. Then step 6 for Greek yogurt: if you want thick Greek yogurt, line a strainer with cheesecloth, set it over a bowl, pour the chilled yogurt in, let it drain for 1-2 hours, the longer you drain, the thicker it gets. That's the "why buy greek" part, you can make it at home for way cheaper. Then next h2: Tips for Success and Reusing Your Starter. That's where we hit the context point: "Once you make this one time, you
