Cubed Jicama — Cups to Grams
1 cup cubed jicama (1/2-inch cubes) = 130 grams. Mexican turnip: sweet, crisp, and white-fleshed. 1 medium jicama (~450g peeled) = 3 cups cubed. Crunchy in salads, fruit cups, and stir-fries. Does not brown after cutting. 8.1g per tablespoon.

Cubed Jicama Weight by Cut
Jicama's density is consistent regardless of cut because the flesh is uniformly dense throughout — unlike vegetables with hollow centers or variable moisture zones. The cup-weight differences between cut styles are entirely explained by how efficiently each cut type packs into a measuring cup.
Small cubes, 1/2 inch (130g/cup): The most efficient packing of jicama cuts. Small cubes settle uniformly with predictable small air gaps between pieces. This is the standard for fruit cups, salads, and most recipe calls for "cubed jicama." A 1/2-inch cube is approximately the same size as a large blueberry or small grape.
Large cubes, 1 inch (120g/cup): Larger cubes leave proportionally larger air gaps between pieces, reducing cup density by approximately 8% compared to small cubes. One-inch cubes are used when jicama is a substantial component of a dish — stir-fries, composed salads, or preparations where you want visible, distinct jicama pieces rather than a mixed element.
Julienned sticks (115g/cup): Long thin matchsticks (approximately 3 inches x 2-3mm square) are the lightest jicama cut per cup because the long thin geometry creates the most air space when stacked randomly in a measuring cup. Julienned jicama is the form used in spring rolls, slaws, and preparations inspired by Vietnamese or Thai cuisine where thin strands are combined with herbs and protein.
Sliced (135g/cup): Thin planks or rounds (3-4mm thick) pack the most efficiently because flat pieces stack with less air space than cubes or sticks. The 135g density is the highest of the jicama forms. Sliced jicama is used as a crudite (served with guacamole or dips), as a vessel for canape toppings (small sliced rounds can be used as cracker substitutes), or in layered salads.

Jicama's Origin and Mexican Street Food Tradition
Jicama (Pachyrhizus erosus) is native to Mexico and was cultivated by Mesoamerican civilizations long before European contact. Archaeological evidence from Mexico suggests jicama cultivation dates back at least 3,000 years. The plant is a legume — its above-ground parts (leaves, seeds, pods) contain rotenone, a natural insecticide that is toxic to humans, fish, and insects, which is why only the root is eaten. Spanish colonizers brought jicama from Mexico to the Philippines in the 16th century via the Manila Galleon trade route, and it spread throughout Southeast Asia — which is why jicama appears in Filipino (singkamas), Indonesian (bengkoang), and Vietnamese (cu dau) cuisines in addition to its Mexican homeland.
In Mexico, jicama's most iconic use is as street food — sold by vendors who peel and slice jicama on-site, serving it in cups or on sticks with fresh-squeezed lime juice, chili powder (or Tajin seasoning), and salt. This preparation is so fundamental to Mexican food culture that "jicama con chile y limon" is essentially a national snack, the equivalent of salted peanuts or popcorn in other food cultures. The same vendor might also offer cucumber, mango, and watermelon prepared the same way — the concept of fresh fruit and vegetable with acid and heat is a cornerstone of Mexican street food.
Jicama is also a significant ingredient in Michoacan and Jalisco cuisines, appearing in ensalada de Nochebuena (Christmas Eve salad traditionally served on December 24th with jicama, oranges, beets, peanuts, and pomegranate seeds) — one of the most visually distinctive traditional Mexican salads.
Jicama's Texture: Why It Stays Crunchy
Jicama's exceptional crunch comes from its cell wall structure and water-to-fiber ratio. The flesh consists of densely packed parenchyma cells with relatively thick, rigid cell walls and high turgor pressure (internal water pressure). When you bite into raw jicama, you are shattering these pressurized cells — the crunch is the sound and sensation of cell walls fracturing under biting pressure.
What makes jicama different from other crisp vegetables is that the cell walls remain rigid through acid exposure. Most crunchy vegetables (cucumber, apple, celery) lose turgor pressure within 15-30 minutes in an acidic dressing as osmosis draws water out of the cells and the cells lose pressure. Jicama's cell walls are reinforced with starch that is less soluble in acidic environments, maintaining cell integrity longer. This is why jicama cubes dressed with lime juice (pH approximately 2.2) stay crunchy for hours rather than minutes — a practical advantage for party salads, fruit cups, and salsas that need to be made in advance.
The inulin content of jicama (approximately 10-12g per 100g) also contributes to texture. Inulin is a prebiotic fiber that forms a gel in the presence of water, contributing to the firm-yet-juicy texture that distinguishes jicama from purely crunchy-dry vegetables like carrot. The inulin also means jicama has a relatively low glycemic index (approximately 16) despite its sweet flavor — the inulin is not fully digested by small intestine enzymes.
Jicama Recipes with Exact Quantities
Ensalada de Nochebuena (Mexican Christmas Eve salad, serves 8): Peel and cube 1 large jicama (600g peeled) = approximately 4.5 cups. Cube 3 medium beets, roasted and cooled (approximately 2 cups). Supreme 4 navel oranges. Combine jicama, beets, and oranges. Add 1/2 cup pomegranate arils, 1/2 cup dry-roasted peanuts. Dress with: 3 tbsp fresh orange juice + 1 tbsp cider vinegar + 1 tbsp honey + 1/4 tsp cinnamon. Toss gently. Serve on a bed of romaine or butter lettuce. The visual contrast of white jicama, red beet, orange segments, and ruby pomegranate seeds is as important as the flavor combination.
Jicama slaw (serves 6): Julienne 450g peeled jicama (approximately 4 cups sticks). Julienne 2 medium carrots (approximately 1.5 cups). Dice 1/2 red onion. Dressing: 3 tbsp fresh lime juice + 2 tbsp rice vinegar + 1 tbsp honey + 1 tbsp neutral oil + 1/4 tsp cumin + 1/4 tsp chili powder + salt. Toss. Rest 15 minutes minimum before serving to allow dressing to soften the vegetables slightly and develop flavor. Serves 6. Excellent alongside grilled fish tacos or as a burrito bowl component.
Jicama and mango salsa (makes 3 cups): 1 cup (130g) small-cubed jicama + 1 cup diced ripe mango + 1/2 cup finely diced red onion + 1 minced jalapeno + 3 tbsp fresh lime juice + 2 tbsp chopped cilantro + salt. Toss and rest 10 minutes before serving. Serve with grilled shrimp, fish, or chicken. Keeps refrigerated 2 days — the jicama maintains its crunch while the mango softens very slightly, creating pleasant textural contrast.
