Flour, water, salt, and something alive to leaven it. Bread is the daily staple that turns a pantry and a mill into an actual meal, and the two paths to get there, commercial yeast and sourdough, are both worth knowing.

Commercial yeast, sold as active dry or instant, is a single fast-acting strain that gives a reliable, relatively quick rise. It's the more forgiving place to start, since the yeast itself doesn't need days of care before a recipe even begins.
Sourdough relies on a starter, a living culture of wild yeast and bacteria maintained in flour and water. It takes longer to develop and asks for regular feeding, but it produces the distinctive tang associated with sourdough bread and doesn't depend on a store-bought packet of yeast at all, which matters if commercial yeast isn't available.
Both paths use the flour covered on the milling grain guide, whether fresh-milled or store-bought, and both reward the same basic attention to temperature and time.
Getting started
Flour, water, salt, and a leavening agent, either commercial yeast or an active sourdough starter, are the only ingredients a real loaf needs. A mixing bowl, a baking vessel (a loaf pan, a Dutch oven, or a plain baking sheet), and an oven cover the equipment side. Nothing about bread baking requires specialized gear to get a genuinely good result.
Temperature is the variable that matters more than any piece of equipment. Yeast is a living organism: it goes dormant in cold conditions and begins to die at high heat, so understanding roughly where dough needs to sit is worth more than a fancy proofing box.
If starting a sourdough culture from scratch, budget several days of daily feeding before the starter is reliably active enough to leaven a loaf on its own. That patience is the real cost of sourdough; everything after is routine.
The work
Mixed dough is generally best around 78°F to 82°F after kneading, with bulk fermentation continuing at roughly 80°F to 85°F. Once shaped, the final proof usually happens closer to 90°F to 100°F, in a draft-free, slightly humid spot; an oven turned on briefly and then off, with a bowl of steaming water inside, works well as an improvised proof box.[1]
Dough is ready to bake when it's roughly doubled in size and springs back slowly, rather than immediately, when pressed with a finger. If it springs back instantly, it needs more time; if it doesn't spring back at all, it's over-proofed and may collapse in the oven.
Yeast is inactive below freezing but not dead, which is why refrigerated or frozen dough needs time to warm before it will rise properly again. High heat is the real threat: temperatures well above the normal proofing range start to damage the yeast and can ruin a rise entirely.
The work
A starter is nothing more than flour and water, fed on a schedule until it develops a stable population of wild yeast and lactic acid bacteria. Those bacteria are doing real work: they produce lactic acid that drops the starter's pH safely below 4.6, which is what gives sourdough its characteristic tang and helps make the culture inhospitable to unwanted organisms.[2]
Starters are most active around 70°F. Refrigeration slows activity considerably, which is useful for stretching feedings out when a starter isn't being used daily, but temperatures that feel genuinely hot to a person can overheat and kill the culture.[3]
Feed regularly, keep the container and utensils clean, and cover the starter loosely rather than sealing it airtight, which discourages mold while still letting the culture breathe.
A dark, alcohol-smelling liquid layer, known as hooch, is a harmless byproduct of fermentation and just means the starter is hungry. Pour it off or stir it in, then feed as usual.[2] A refrigerated starter that's gone a while between feedings may also develop whitish clumps on the surface; these are typically safe yeasts, not mold.[2]
Actual mold looks different: fuzzy, raised, or unusually colored. If a starter develops mold, discard the whole culture rather than scooping around the affected spot, and start fresh with clean equipment.[3] Milk-and-sugar "friendship bread" style starters carry an added note of caution: their richer ingredients create conditions that have, in rare cases, supported harmful microorganisms, so the same clean, regular-feeding discipline matters even more for those variants.[2]
Common first-loaf mistakes
Water that's genuinely hot to the touch can damage or kill commercial yeast before baking even starts. Warm, not hot, is the target; a thermometer removes the guesswork.
A starter needs consistent daily feeding for several days before it's reliably strong enough to leaven bread. Trying to bake with an underdeveloped starter usually produces a dense, flat loaf, not a failed starter.
Mold reaches further into a culture than what's visible on the surface. Removing the visible patch and continuing to feed the rest doesn't remove the contamination.
A drafty, cold kitchen slows fermentation dramatically; a spot near a heat source can overheat dough and hurt both flavor and structure. A consistent, moderate spot beats either extreme.
